Subject [jira] [Commented] (HBASE-17350) Fixup of regionserver group-based assignment
Date Wed, 18 Jan 2017 22:32:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15828887#comment-15828887

Francis Liu commented on HBASE-17350:
-------------------------------------

{quote}
The commands are named inconsistently. Usually it is verb with a rsgroup suffix but we have
get_table_rsgroups and then move_rsgoup_tables. Ditto for servers.
{quote}
The rsgroup used here is not a "suffix" but actually part of describing the command. So you'd
like to keep the suffix in the same place? 

ie
get_table_rsgroup - get a table's rsgroup
move_rsgoup_tables - move to rsgroup some tables
move_rsgroup_servers - move to rsgroup some servers

> Can we do some fixup on the regionserver group-based assignement before it makes it into
a release? Here are a few items after trying to use it last night:
> + The commands are named inconsistently. Usually it is verb with a rsgroup suffix but
we have get_table_rsgroups and then move_rsgoup_tables. Ditto for servers.
> + In local mode, the regionserver doesn't belong to a group. Shouldn't it?
> + Adding a server to a group with the move_rsgroup_tables is non-intuitive, to me at
least (especially given #2 above).
> + The error message you get when you run one of these rsgroup commands should tell you
how to set up rsgroups rather than dump out a cryptic exception.
> Thats all for now.
