stack commented on HBASE-20893:
-------------------------------
[~allan163] Yeah, support for rollback at the split procedure level was added
but rollback invokes rolling back of subprocedures and this does not work if
subprocedure is unassign.
Yeah, unsupported and CODE-BUG as well as crashed out procedure are scary.
bq. But. since a exception is thrown, the decrease for stateCount never happen.
Lets fix.
Do you have a problem with this patch? It avoids CODE-BUG and skips use of
rollback. I'm in here because my long-running tests are failing and this looks
to be the cause.
