The message I responded to stated 100% to 200% Catalog CPU usage, which
means 1 to 2 cores fully used, which translates to 1 to 2 threads actually
loading (and the other 15 or 14 possibly waiting on the same tables).
That's behavior consistent with IMPALA-4765.

There could be other reasons for this behavior.  I'm not saying IMPALA-4765
is the root cause in this case, just that the described behavior matches
the known issue.
