IMPALA-8121: part 1: some test fixes for catalog v2
This fixes some test issues encountered when running the
tests against a cluster with catalog V2 enabled, meaning
the local catalog with HMS notifications enabled. More
fixes are to come but I preferred to do them in smaller
batches as they're ready.
Test fixes:
* Detect whether catalog v2 features are enabled from web UI.
* test_describe_db waits for metadata event processor to pick up new
database and doesn't need to change database owner
* TestWebPage.test_catalog handles an expected exception from
the /catalog_objects page on the impalad.
* test_pull_stats_profile: feature disabled with local catalog
* test_hms_service_dies: invalidate the test table instead of
the whole catalog.
* test_compute_stats: Avro schema resolution behaviour changed
with local catalog - IMPALA-7308
Some remaining issues:
* IMPALA-8458
* IMPALA-8459
* IMPALA-7131 (data sources)
* getTables() doesn't return comment

> Support external data sources without catalogd
> ----------------------------------------------
>
> Key: IMPALA-7131
> URL: https://issues.apache.org/jira/browse/IMPALA-7131
> Project: IMPALA
> Issue Type: Sub-task
> Components: Catalog, Frontend
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Minor
>
> Currently it seems that external data sources are not persisted except in
> memory on the catalogd. This means that it will be somewhat more difficult to
> support this feature in the design of impalad without a catalogd.
> This JIRA is to eventually figure out a way to support this feature -- either
> by supporting in-memory on a per-impalad basis, or perhaps by figuring out a
> way to register them persistently in a file system directory, etc.
