Subject [jira] [Commented] (HBASE-7824) Improve master start up time when there is log splitting work
Date Sat, 16 Mar 2013 05:26:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13604123#comment-13604123

Lars Hofhansl commented on HBASE-7824:
--------------------------------------

Maybe I was a bit rash here.
You said you worked on figuring out what the issues was with the failed test. Any luck?

The fix that Ram suggests in HBASE-7985 does not work?
This is a good improvement and it would be a shame to miss out on this in 0.94.

> When there is log split work going on, master start up waits till all log split work
completes even though the log split has nothing to do with meta region servers.
> It's a bad behavior considering a master node can run when log split is happening while
its start up is blocking by log split work. 
> Since master is kind of single point of failure, we should start it ASAP.
