Hudson commented on HBASE-16519: -------------------------------- FAILURE: Integrated in Jenkins build HBase-Trunk_matrix #1517 (See [https://builds.apache.org/job/HBase-Trunk_matrix/1517/]) HBASE-16519 Procedure v2 - Avoid sync wait on DDLs operation (addendum) (matteo.bertozzi: rev 847955427528bb9edff44fb6b2969fc9dfd8b9cc) * (edit) hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestAssignmentManagerMetrics.java > Procedure v2 - Avoid sync wait on DDLs operation > ------------------------------------------------ > > Key: HBASE-16519 > URL: https://issues.apache.org/jira/browse/HBASE-16519 > Project: HBase > Issue Type: Sub-task > Components: master, proc-v2 > Affects Versions: 2.0.0 > Reporter: Matteo Bertozzi > Assignee: Matteo Bertozzi > Fix For: 2.0.0 > > Attachments: HBASE-16519-addendum.patch, HBASE-16519-v0.patch > > > Some operation ModifyColumnFamily, AddDeleteColumnFamily, DeleteColumnFamily, > ModifyTable, TruncateTable are still synchronous on the master side. with a > wait until the operation completes before returning. > this was done to keep the sync behavior for old client. but instead of using > the procLatch which recognize the client version and decide if the operation > should be sync or not it just always wait. making the client side proc fault > tolerance ineffective. > also the add/delete/modifyColumnFamily operation does not seems to follow the > Async() naming in master. and the comment claim to be async but everyone uses > them as sync.
