> IMPALA-9731 dropped support for Hive 2 and removed most code associated with it.
> However we still have if statements that check MetastoreShim.getMajorVersion().
> One can check it with:
> {noformat}
> git grep getMajorVersion
> {noformat}
> It would be nice to get rid of these because the MetastoreShim.getMajorVersion() == 2 branches are dead code now.
> Moreover, in the test code there are still some places that check for HIVE_MAJOR_VERSION == 2, e.g.:
> https://github.com/apache/impala/blob/c10e7c969dfcc4847a8f7708940f4aa1852dbee4/tests/metadata/test_hms_integration.py#L215
> These can be also removed.
