------------------------------
Hi ~ [~cheersyang] Please help me review this patch.
> fix wrong command in TimelineServiceV2.md
> ------------------------------------------
>
> Key: YARN-9365
> URL: https://issues.apache.org/jira/browse/YARN-9365
> Project: Hadoop YARN
> Issue Type: Bug
> Components: timelineserver
> Affects Versions: 3.2.0, 3.1.1
> Reporter: runlin
> Priority: Major
> Attachments: YARN-9365.patch
>
>
> In TimelineServiceV2.md 255，The step to create the timeline service schema
> does not work
>
> {noformat}
> Finally, run the schema creator tool to create the necessary tables:
> bin/hadoop
> org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator
> -create{noformat}
>
> should be
>
> {noformat}
> The schema creation can be run on the hbase cluster which is going to store
> the timeline
> service tables. The schema creator tool requires both the
> timelineservice-hbase as well
> as the hbase-server jars. Hence, during schema creation, you need to ensure
> that the
> hbase classpath contains the yarn-timelineservice-hbase jar.
> On the hbase cluster, you can get it from hdfs since we placed it there for
> the
> coprocessor in the step above.
> ```
> hadoop fs -get
> /hbase/coprocessor/hadoop-yarn-server-timelineservice-hbase-client-${project.version}.jar
> hadoop fs -get
> /hbase/coprocessor/hadoop-yarn-server-timelineservice-${project.version}.jar
> hadoop fs -get
> /hbase/coprocessor/hadoop-yarn-server-timelineservice-hbase-common-${project.version}.jar
> <local-dir>/.
> ```
> Next, add it to the hbase classpath as follows:
> ```
> export
> HBASE_CLASSPATH=$HBASE_CLASSPATH:/home/yarn/hadoop-current/share/hadoop/yarn/timelineservice/hadoop-yarn-server-timelineservice-hbase-client-${project.version}.jar
> export
> HBASE_CLASSPATH=$HBASE_CLASSPATH:/home/yarn/hadoop-current/share/hadoop/yarn/timelineservice/hadoop-yarn-server-timelineservice-${project.version}.jar
> export
> HBASE_CLASSPATH=$HBASE_CLASSPATH:/home/yarn/hadoop-current/share/hadoop/yarn/timelineservice/hadoop-yarn-server-timelineservice-hbase-common-${project.version}.jar
> ```
> Finally, run the schema creator tool to create the necessary tables:
> ```
> bin/hbase
> org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator
> -create
> ```{noformat}
