Subject [jira] [Commented] (YARN-6316) Provide help information and documentation for TimelineSchemaCreator
Date Fri, 12 May 2017 17:18:04 GMT

    [ https://issues.apache.org/jira/browse/YARN-6316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16008411#comment-16008411

Vrushali C commented on YARN-6316:
----------------------------------

Thanks [~haibochen] for the patch.

1) Could we also update the documentation to reflect that to create tables, pass in that argument.
Default prints usage etc.

2) I was wondering if I can make another addition suggestion. For the schema creation command
in the docs, can we change "hbase" to "hadoop", because the hbase cluster may not have the
timeline service jars because it might be running hadoop 2.5 . But the hadoop cluster on which
we want to enable atsv2 will have the jars and the create table should be run from that cluster.

{code}
bin/hbase org.apache.hadoop.yarn.server.timelineservice.storage.TimelineSchemaCreator
{code}

> Right now there is no help information for timeline schema creator. We may probably want
to provide an option to print help. Also, ideally, if users passed in no argument, we may
want to print out help, instead of directly create the tables. This will simplify cluster
operations and timeline v2 deployments.
