Ringhofer, Impala Public Jenkins,

IMPALA-13631: (Addendum) Test slow concurrent alters
Adds a test that multiple slow concurrent alters complete in parallel
rather than being executed sequentially.
The test creates tables, and ensures Impala's catalog is up-to-date for
their creation so that starting ALTER TABLE will be fast. Then starts
two ALTER TABLE RENAMES asynchronously - with debug_action ensuring each
takes at least 5 seconds - and waits for them to finish.
Verifies that concurrent alters are no longer blocked on "Got catalog
version read lock" and complete in less than 10 seconds.
