Michael Stack 72c3d27bf6 HBASE-20173 [AMv2] DisableTableProcedure concurrent to ServerCrashProcedure can deadlock ... Allow that DisableTableProcedue can grab a region lock before ServerCrashProcedure can. Cater to this cricumstance where SCP was not unable to make progress by running the search for RIT against the crashed server a second time, post creation of all crashed-server assignemnts. The second run will uncover such as the above DisableTableProcedure unassign and will interrupt its suspend allowing both procedures to make progress. M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto Add new procedure step post-assigns that reruns the RIT finder method. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java Make this important log more specific as to what is going on. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java Better explanation as to what is going on. M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/ServerCrashProcedure.java Add extra step and run handleRIT a second time after we've queued up all SCP assigns. Also fix a but. SCP was adding an assign of a RIT that was actually trying to unassign (made the deadlock more likely).		2018-03-13 06:04:36 -07:00
