[jira] [Commented] (HBASE-19620) Add UT to confirm the race in
MasterRpcServices.getProcedureResult
[ https://issues.apache.org/jira/browse/HBASE-19620?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16309354#comment-16309354 ]
Duo Zhang commented on HBASE-19620:
-----------------------------------
Implement a dummy procedure which will block in rollback to make sure that we can hit the race.
If I revert the code of getProcedureResult to the version before HBASE-19608, I will get this
