Subject [jira] [Commented] (HBASE-5782) Not all the regions are getting assigned after the log splitting.
Date Mon, 16 Apr 2012 18:56:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5782?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13254917#comment-13254917

Zhihong Yu commented on HBASE-5782:
-----------------------------------

bq. If this is right, then we should pull back HBASE-4487 or add more locks
Adding more locks would take more time to validate / test.

In order to get 0.94.0 out the door, can we pull back HBASE-4487 in 0.94 and pursue the locking
approach in trunk (or separate branch) ?
