Todd Lipcon resolved IMPALA-2649.
---------------------------------
    Resolution: Fixed

I'm inclined to call this one fixed after a number of changes last year:
- incremental stats data isn't published as part of the metadata objects to impalads, but instead fetched on demand for COMPUTE INCREMENTAL STATS
- incremental stats data are now stored compressed and in byte[] instead of base64-encoded Strings
- generally more work went into catalogd memory management, such as automatic invalidation when running low on heap, so this won't take down catalogd anymore
