----------------------------
Summary: 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: 3.1.1, 3.2.0
Reporter: runlin
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}
