Philip Zeyliger commented on IMPALA-7498:
-----------------------------------------

There's a similar issue with the catalog, which fails (in an unpleasant, core-dump-y way) if it can't talk to the Hive metastore. To be consistent, we should wait a certain amount of time in all cases. (No obligation to fix this together; just mentioning it if you end up in the same code.)

> If you start all daemons simultaneously, impalad with --use_local_catalog enabled will retry three times in a tight loop trying to fetch the DB names, and then exit. Instead it should loop for some amount of time waiting for the catalog to be ready in the same way that the existing implementation does.
