Subject [jira] [Commented] (HBASE-13925) Use zookeeper multi to clear znodes in ZKProcedureUtil
Date Tue, 30 Jun 2015 18:39:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13925?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14608835#comment-14608835

Enis Soztutar commented on HBASE-13925:
---------------------------------------

bq. I think we can pick back the patch for HBASE-7847 to 0.98 and 1.0 with only minor fuzz
and then the patch here would just about apply. Curious what Enis says before proceeding.
It is not immediately clear to me what racing condition this and HBASE-7847 solves. But since
we use multi for most of the operations it will not hurt to use it for delete recursive as
well. 
I'll say we should backport both patches to 0.98 and 1.0 if we can identify a concurrency
issue that it addresses. Lacking that, I would be +0.
