Thiruvel Thirumoolan commented on HBASE-19756: ---------------------------------------------- [~apurtell]/[~yuzhih...@gmail.com] - The master patch here is fine, I wanted to rework on branch-1 patch, but fell sick and patch got committed within that. Raised HBASE-19996 as a followup to fix the problem with branch-1 patch. > Master NPE during completed failed proc eviction > ------------------------------------------------ > > Key: HBASE-19756 > URL: https://issues.apache.org/jira/browse/HBASE-19756 > Project: HBase > Issue Type: Bug > Affects Versions: 1.4.0, 1.3.1 > Reporter: Thiruvel Thirumoolan > Assignee: Thiruvel Thirumoolan > Priority: Major > Fix For: 2.0.0, 3.0.0, 1.3.2, 1.4.1, 1.5.0 > > Attachments: HBASE-19756.branch-1.4.001.patch, > HBASE-19756.branch-1.4.002.patch, HBASE-19756.branch-1.4.003.patch, > HBASE-19756.master.001.patch > > > When procedures like Create table fails due to say AccessDeniedException, > then a rollback procedure is created.
