[jira] [Commented] (HBASE-20642) IntegrationTestDDLMasterFailover throws 'InvalidFamilyOperationException

["Josh Elser (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-20642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16508792#comment-16508792 ] 

Josh Elser commented on HBASE-20642:
------------------------------------

{quote}if we fix HBASE-20658 by releasing the latch after some pre-checks for Modify and Truncate table , then probably we may not need to do nonce check as retry mechanism will not kick in if the procedure is submitted successfully.
{quote}
I think in both cases, we don't want to release those latches early (would break functionality of Truncate, and regress on HBASE-19953 for modify table). However, using the same nonce from the client seems like the right fix to me.

We have _one_ client and this client is (unwittingly) submitting the same procedure multiple times. I don't think I've seen any reason that this should be using a new nonce – so let's make the nonce help us in this known-deficient case :)
