Duo Zhang commented on HBASE-27277:
-----------------------------------
Saw this in the test output
{noformat}
2023-04-07T13:52:53,904 DEBUG [RegionServerTracker-0]
assignment.RegionRemoteProcedureBase(122): pid=10, ppid=7, state=RUNNABLE,
hasLock=false; OpenRegionProcedure dd97971f0a037756d8b0365e8a42cda8,
server=c17ceca693c4,45433,1680875568871 for region state=OPENING,
location=c17ceca693c4,45433,1680875568871, table=Race,
region=dd97971f0a037756d8b0365e8a42cda8, targetServer
c17ceca693c4,45433,1680875568871 is dead, SCP will interrupt us, give up
{noformat}
So the TRSp will hang there and the UT will be blocked at line 154 forever.
I think this should be a test issue. Let me think how to fix it.
