fix wrong command in TimelineServiceV2.md

Finally, run the schema creator tool to create the necessary tables:

    bin/hadoop org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator -create

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
```
