Ben Lau created HBASE-19989: ------------------------------- Summary: READY_TO_MERGE and READY_TO_SPLIT do not update region state correctly Key: HBASE-19989 URL: https://issues.apache.org/jira/browse/HBASE-19989 Project: HBase Issue Type: Bug Affects Versions: 1.4.1, 1.3.1 Reporter: Ben Lau Assignee: Ben Lau
Region state transitions do not work correctly for READY_TO_MERGE/SPLIT. [~thiruvel] and I noticed this is due to break statements being in the wrong place in AssignmentManager. This allows a race condition for example in which one of the regions being merged could be moved concurrently, resulting in the merge transaction failing and then double assignment and/or dataloss. This bug appears to only affect branch-1 (for example 1.3 and 1.4) and not branch-2 as the relevant code in AM has since been rewritten. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
