Scenarios and versions of each component​

Deployment sequence​

You can select and adjust the sequence after serial number 3 However, one thing to pay attention to when deploying exchangis is to copy the sqoop engine plug-in of exchangis to the engine plug-in package under lib of linkis Schedulis, qualitis, exchangis, streamis, visualis and other systems are integrated with DSS through their respective appconn. Note that after integrating the component appconn, restart the service module corresponding to DSS or restart DSS

1. linkis
2. DataSphereStudio
3. Schedulis
4. Qualitis
5. Exchangis
6. Streamis
7. Visualis

If you integrate skywalking, you can see the service status and connection status in the extended topology diagram, as shown in the following figure: At the same time, you can also clearly see the call link in the trace, as shown in the following figure, which is also convenient for you to locate the error log file of the specific service

Dependency adjustment and packaging​

The getfield method in sparkscalaexecutor needs to adjust the following code

protected def getField(obj: Object, name: String): Object = {
    // val field = obj.getClass.getField(name)
    val field = obj.getClass.getDeclaredField("in0")

The pom file of linkis-engineplugin-flink​

<flink.version>1.13.2</flink.version>

Due to the adjustment of some classes in Flink 1.12.2 and 1.13.2, we refer to the temporary "violence" method given by the community students: copy the classes in part 1.12.2 to 1.13.2, adjust the scala version to 12, and compile them by ourselves It involves the specific modules of flink: flink-sql-client_${scala.binary.version}

-- Note that the following classes are copied from 1.12.2 to 1.13.2
org.apache.flink.table.client.config.entries.DeploymentEntry
org.apache.flink.table.client.config.entries.ExecutionEntry

Compilation error troubleshooting​

• If there is an error when you compile, try to enter a module to compile separately to see if there is an error and adjust it according to the specific error
• For example, the following example (the py4j version does not adapt when the group Friends adapt to the lower version of CDH): if you encounter this problem, you can adjust the version with the corresponding method to determine whether to adapt

Installation deployment​

Official deployment address Common error address

Path unification​

It is recommended to deploy the relevant components in the same path (for example, I unzip them all in /home/hadoop/application)

Notes on linkis deployment​

Deploy config folder​

db.sh, the address of the links connection configured by mysql, and the metadata connection address of hive linkis-env.sh

-- The path to save the script script. Next time, there will be a folder with the user's name, and the script of the corresponding user will be stored in this folder
WORKSPACE_USER_ROOT_PATH=file:///home/hadoop/logs/linkis
-- Log files for storing materials and engine execution
HDFS_USER_ROOT_PATH=hdfs:///tmp/linkis
-- Log of each execution of the engine and information related to starting engineconnexec.sh
ENGINECONN_ROOT_PATH=/home/hadoop/logs/linkis/apps
-- Access address of yarn master node (active resource manager)
YARN_RESTFUL_URL
-- Conf address of Hadoop / hive / spark
HADOOP_CONF_DIR
HIVE_CONF_DIR
SPARK_CONF_DIR
-- Specify the corresponding version
SPARK_VERSION=3.0.1
HIVE_VERSION=3.1.2
-- Specify the path after the installation of linkis. For example, I agree to specify the path under the corresponding component here
LINKIS_HOME=/home/hadoop/application/linkis/linkis-home

flink​

If you use Flink, you can try importing it from flink-engine.sql into the database of linkis

Need to modify @Flink_LABEL version is the corresponding version, and the queue of yarn is default by default

At the same time, in this version, if you encounter the error of "1g" converting digital types, try to remove the 1g unit and the regular check rules. Refer to the following:

lzo​

If your hive uses LZO, copy the corresponding LZO jar package to the hive path. For example, the following path:

lib/linkis-engineconn-plugins/hive/dist/v3.1.2/lib

Frequently asked questions and precautions​

• The MySQL driver package must be copied to /lib/linkis-commons/public-module/ and /lib/linkis-spring-cloud-services/linkis-mg-gateway/
• Initialization password in conf/linkis-mg-gateway.properties -> wds.linkis.admin.password
• ps-cs in the startup script,there may be failures, if any,use sh linkis-daemon.sh ps-cs , start it separately
• At present, if there is time to back up the log, sometimes if the previous error log cannot be found, it may be backed up to the folder of the corresponding date
• At present lib/linkis-engineconn-plugins have only spark/shell/python/hive,If you want appconn, flink and sqoop, go to DSS, linkis and exchangis to get them
• Configuration file version check

linkis.properties,flink see if it is used
wds.linkis.spark.engine.version=3.0.1
wds.linkis.hive.engine.version=3.1.2
wds.linkis.flink.engine.version=1.13.2

Error record​

1. Incompatible versions. If you encounter the following error, it is whether the scala version is not completely consistent. Check and compile it

2. Yarn configures the active node address. If the standby address is configured, the following error will appear:

Considerations for DSS deployment​

Official installation document

config folder​

db.sh: configure the database of DSS config.sh

-- The installation path of DSS, for example, is defined in the folder under DSS
DSS_INSTALL_HOME=/home/hadoop/application/dss/dss

conf folder​

dss.properties

# Mainly check whether spark / hive and other versions are available. If not, add
wds.linkis.spark.engine.version=3.0.1
wds.linkis.hive.engine.version=3.1.2
wds.linkis.flink.engine.version=1.13.2

dss-flow-execution-server.properties

# Mainly check whether spark / hive and other versions are available. If not, add
wds.linkis.spark.engine.version=3.0.1
wds.linkis.hive.engine.version=3.1.2
wds.linkis.flink.engine.version=1.13.2

If you want to use dolphin scheduler for scheduling, please add the corresponding spark / hive version to this pr Reference pr

dss-appconns​

Exchangis, qualitis, streamis and visualis should be obtained from the projects of exchangis, qualitis, streamis and visualis respectively

Frequently asked questions and precautions​

• Since we integrate scheduleis, qualitis, exchangis and other components into DSS, all the interfaces of these components will be called synchronously when creating a project, so we ensure that dss_appconn_instance configuration paths in the instance are correct and accessible
• The Chrome browser recommends that the kernel use version 100 or below. Otherwise, there will be a problem that you can separate scdulis, qaulitis and other components, but you cannot log in successfully through DSS
• Hostname and IP. If IP access is used, make sure it is IP when executing appconn-install.sh installation Otherwise, when accessing other components, you will be prompted that you do not have login or permission

Schedulis deployment considerations​

Official deployment document

conf folder​

azkaban.properties

# azkaban.jobtype.plugin.dir and executor.global.properties. It's better to change the absolute path here
# Azkaban JobTypes Plugins
azkaban.jobtype.plugin.dir=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_exec/plugins/jobtypes

# Loader for projects
executor.global.properties=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_exec/conf/global.properties

# Engine version
wds.linkis.spark.engine.version=3.0.1
wds.linkis.hive.engine.version=3.1.2
wds.linkis.flink.engine.version=1.13.2

web modular​

plugins/viewer/system/conf: Here, you need to configure the database connection address to be consistent with scheduleis azkaban.properties: Configuration of user parameters and system management

viewer.plugins=system
viewer.plugin.dir=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_web/plugins/viewer

Frequently asked questions and precautions​

If there are resources or there are no static files such as CSS in the web interface, change the relevant path to an absolute path If the configuration file cannot be loaded, you can also change the path to an absolute path For example:

### web module
web.resource.dir=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_web/web/
viewer.plugin.dir=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_web/plugins/viewer

### exec module
azkaban.jobtype.plugin.dir=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_exec/plugins/jobtypes
executor.global.properties=/home/hadoop/application/schedulis/apps/schedulis_0.7.0_exec/conf/global.properties

Considerations for qualitis deployment​

Official deployment document

conf folder​

application-dev.yml

  # The correct spark version is configured here
  spark:
    application:
      name: IDE
      reparation: 50
    engine:
      name: spark
      version: 3.0.1

Exchange deployment considerations​

Official deployment document

Frequently asked questions and precautions​

If you click the data source and there is an error that has not been published, you can try to add linkisps_dm_datasource -> published_version_id Modify the published_version_id value to 1 (if it is null)

Visualis​

Official deployment document

Frequently asked questions and precautions​

If the preview view is inconsistent, please check whether the bin / phantomjs file is uploaded completely If you can see the following results, the upload is complete

./phantomjs -v
2.1.1

Streamis​

Official deployment document

dss-appconn​

Qualitis, exchangis, streams and visualis are compiled from various modules, copied to DSS appconns under DSS, and then executed appconn-install.sh under bin to install their components If you find the following SQL script errors during integration, please check whether there are comments around the wrong SQL. If so, delete the comments and try appconn install again For example, for qualitis, the following IP and host ports are determined according to their specific use

qualitis
127.0.0.1
8090

Nginx deployment example​

linkis.conf: dss/linkis/visualis front end exchangis.conf: exchangis front end streamis.conf: streamis front end Scheduling and Qaulitis are in their own projects Linkis / Visualis needs to change the dist or build packaged from the front end to the name of the corresponding component here
