IMPALA-8369 : Fix for tests failing with incompatible column changes
In Hive-3 the configuration for allowing users to make incompatible
column type changes was disabled by default. In Hive-2 this was allowed.
Some of the tests like data_errors/test_data_errors.py and
metadata/test_compute_stats.py make changes to column types which are
disallowed by HMS-3 by default. This change adds a configuration option
in hive-site.xml to allow making incompatible changes to column types so
that we can run the existing tests with HMS-3.
Also, in HMS-3 there are certain new event types (OPEN_TXN, COMMIT_TXN,
etc) which may not have dbname set. This breaks the assumption in the
code in EventProcessor which expects dbName_ to be not null at all
times. This patch also makes changes in the EventProcessor so that such
Ignored events do not fail precondition checks during event processing.

> Project: IMPALA
> Issue Type: Improvement
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
> Labels: impala-acid
>
> Currently, Impala only works with Hive 2.1.1. Since Hive 3.1.0 has been
> released for a while it would be good to add support for Hive 3.1.0 (HMS
> 3.1.0). This patch will focus on ability to connect to HMS 3.1.0 and run
> existing tests. It will not focus on adding support for newer features like
> ACID in Hive 3.1.0 which can be taken up as separate JIRA.
> It would be good to make changes to Impala source code such that it can work
> with both Hive 2.1.0 and Hive 3.1.0 without the need to create a separate
> branch. However, this should be a aspirational goal. If we hit a blocker we
> should investigate alternative approaches.
