IMPALA-8177: Log DDL failures in coordinator logs
If a DDL fails for some reason, it helps to log the failure message in
the coordinator logs so that we can differentiate between failed and
successful DDL queries.
For ex:
[0d66cd6004b4:21000] default> drop database foo;
Query: drop database foo
ERROR: ImpalaRuntimeException: Error making 'dropDatabase' RPC to Hive
Metastore:
CAUSED BY: NoSuchObjectException: foo

-------------------------------
Testing: Verified manually by running a few DDLs that fail and then inspecting
the coordinator log file.

> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Catalog
> Affects Versions: Impala 2.13.0, Impala 3.1.0

>
> I ran into this issue while debugging DDL failures.
> If a DDL fails for some reason, we propagate the error back to the shell and
> update the runtime profile, but we do not log the failure message to the
> coordinator logs. This means that the coordinator side logging remains the
> same for both successful and failed DDL queries.
> We need to log the failure status in the coordinator logs so that it is easy
> to differentiate successful vs failed queries.
