Umesh Agashe created HBASE-19851: ------------------------------------ Summary: ProcV2 framework's rollback() needs to maintain stack like execute() Key: HBASE-19851 URL: https://issues.apache.org/jira/browse/HBASE-19851 Project: HBase Issue Type: Improvement Components: proc-v2 Affects Versions: 2.0.0-beta-1 Reporter: Umesh Agashe Fix For: 2.0.0
Refer to HBASE-19839 and detailed description there. Bug showed up as a flaky test TestMergeTableRegionsProcedure.testRollbackAndDoubleExecution(). In short, when rollback() is called after step 5 (MERGE_TABLE_REGIONS_CLOSE_REGIONS), rollback of the procedure tries to reassign two regions that are to be merged. It spawns 2 AssignProcedures and don't wait on them to finish. Rollback should have ability to have sub-procedures and separate proc stack. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
