Subject [jira] [Commented] (HBASE-9775) Client write path perf issues
Date Fri, 18 Oct 2013 15:20:48 GMT

    [ https://issues.apache.org/jira/browse/HBASE-9775?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13799187#comment-13799187

Nicolas Liochon commented on HBASE-9775:
----------------------------------------

On failure, receiveMultiAction finishes when it submit another task, so it's not really recursive.
It is recursive if we receive an exception rather than a response; but this path is actually
not used (I've got a fix for this, but I prefer to wait for the post RC).
I've done a small test with 3 nodes, kill-9ing nodes, the number of task stayed as expected.
