Duo Zhang commented on HBASE-21323:
-----------------------------------
Oh I mean we can revert the patch first to make the build clean. And then let's
try to find out the reason why branch-2.1 and branch-2.0 have a different
behavior before re apply the patch here.
We will delete all the sub procedures at once when the root procedure is
finished, and in this test, the root procedure is hung, so the DummyProcedure,
which is a sub procedures, should not be purged... You can apply the patch to
branch-2.1 or branch-2.0, and add some breakpoints in the loadProcedures method
of ProcedureExecutor to see what's going on.
Thanks.
