Tim Armstrong updated IMPALA-6924:
----------------------------------
Description:
"Compute stats" queries spawn off child queries that do most of the work. It's
non-trivial to track down the child queries and get their profiles if something
goes wrong. We really should have, at a minimum, the query IDs of the child
queries in the parent's profile and vice-versa.
