Szehon Ho commented on HIVE-9060:
---------------------------------

[~xuefuz] can you review if you get a chance?  The test failure doesn't look related, as it
is in other runs as well.

single operator.  However, some references to the old (removed) child still remain in the
optimizer context, and mess up further optimizer procs.
