We need about 7 minutes to assign 500 regions, so when we want to unassign the 500 regions we will timeout... https://builds.apache.org/job/HBase-Flaky-Tests/job/master/111/artifact/hbase-server/target/surefire-reports/org.apache.hadoop.hbase.master.procedure.TestCreateTableProcedure-output.txt/*view*/ > Introduce a region transition procedure to handle all the state transition > for a region > --------------------------------------------------------------------------------------- > > Key: HBASE-20881 > URL: https://issues.apache.org/jira/browse/HBASE-20881 > Project: HBase > Issue Type: Sub-task > Components: amv2, proc-v2 > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Major > Fix For: 3.0.0, 2.2.0 > > Attachments: HBASE-20881-v1.patch, HBASE-20881-v10.patch, > HBASE-20881-v11.patch, HBASE-20881-v12.patch, HBASE-20881-v13.patch, > HBASE-20881-v13.patch, HBASE-20881-v14.patch, HBASE-20881-v14.patch, > HBASE-20881-v15.patch, HBASE-20881-v16.patch, HBASE-20881-v2.patch, > HBASE-20881-v3.patch, HBASE-20881-v4.patch, HBASE-20881-v4.patch, > HBASE-20881-v5.patch, HBASE-20881-v6.patch, HBASE-20881-v7.patch, > HBASE-20881-v7.patch, HBASE-20881-v8.patch, HBASE-20881-v9.patch, > HBASE-20881.patch > > > Now have an AssignProcedure, an UnssignProcedure, and also a > MoveRegionProcedure which schedules an AssignProcedure and an > UnssignProcedure to move a region. This makes the logic a bit complicated, as > MRP is not a RIT, so when SCP can not interrupt it directly... -- This message was sent by Atlassian JIRA (v7.6.3#76005)
