ramkrishna.s.vasudevan updated HBASE-7103: ------------------------------------------ Attachment: HBASE-7103_0.94.patch > Need to fail split if SPLIT znode is deleted even before the split is > completed. > -------------------------------------------------------------------------------- > > Key: HBASE-7103 > URL: https://issues.apache.org/jira/browse/HBASE-7103 > Project: HBase > Issue Type: Bug > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > Fix For: 0.94.3, 0.96.0 > > Attachments: 7103-6088-revert.txt, HBASE-7103_0.94.patch, > HBASE-7103_0.94.patch, HBASE-7103_testcase.patch, HBASE-7103_trunk.patch > > > This came up after the following mail in dev list > 'infinite loop of RS_ZK_REGION_SPLIT on .94.2'. > The following is the reason for the problem > The following steps happen > -> Initially the parent region P1 starts splitting. > -> The split is going on normally. > -> Another split starts at the same time for the same region P1. (Not sure > why this started). > -> Rollback happens seeing an already existing node. > -> This node gets deleted in rollback and nodeDeleted Event starts. > -> In nodeDeleted event the RIT for the region P1 gets deleted. > -> Because of this there is no region in RIT. > -> Now the first split gets over. Here the problem is we try to transit the > node to SPLITTING to SPLIT. But the node even does not exist. > But we don take any action on this. We think it is successful. > -> Because of this SplitRegionHandler never gets invoked. -- This message is automatically generated by JIRA.
