Subject [jira] [Commented] (HBASE-5715) Revert 'Instant schema alter' for now, HBASE-4213
Date Wed, 04 Apr 2012 17:19:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5715?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13246490#comment-13246490

Subbu M Iyer commented on HBASE-5715:
-------------------------------------

I reviewed the thread above and I do see mixed feeling about this. 

So, just wanted to clarify whether addressing the monitoring leaks (5702), introduce throttling
to address rapid open/close region concerns (5713) and addressing the ambiguity in the flags
that enables/disables this feature is even an option or not?

I can take up addressing the above two minor issues if that's an option. Also, since the default
alter does not go through this path the impact to the common user should be none. 

Please note that what we have is based on loose set of requirements and I sincerely think
that what is lacking is rock solid testing in a production kind-of environment and having
cycles to address the issues if any.
