Subject [jira] [Commented] (HBASE-13394) Failed to recreate a table when quota is enabled
Date Fri, 24 Apr 2015 17:04:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13394?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14511342#comment-14511342
] 

Matteo Bertozzi commented on HBASE-13394:
-----------------------------------------

[~ashish singhi] you can do the branch-1 patch. branch-1 has the option to use handlers. 
so you use what I've done in v4 for the procedure side, but have to keep the checkNamespaceTableAndRegionQuota()
in HMaster and you add your try/catch in HMaster (this stuff is only in the "don't use procedure"
if branch)

> Enable quota by setting {{hbase.quota.enabled}} to true
> Create a table say with name 't1', make sure the creation fails after adding  this table
entry into namespace quota cache.
> Now correct the failure and recreate the table 't1'. It fails with below exception.
