Andrew Purtell reopened HBASE-19989: ------------------------------------ The new tests TestZKLessMergeOnCluster and TestZKLessSplitOnCluster consistently fail for me on branch-1.3 and branch-1.4. {code} java.lang.RuntimeException: org.apache.hadoop.hbase.exceptions.DeserializationException: Missing pb magic PBUF prefix {code} > 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: 1.3.1, 1.4.1 > Reporter: Ben Lau > Assignee: Ben Lau > Priority: Major > Fix For: 1.3.2, 1.5.0, 1.4.3 > > Attachments: HBASE-19989-branch-1.patch > > > 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)
