Description

We should consider backporting parts of the change that enabled Decimal V2 by default to the 2.x branch: https://gerrit.cloudera.org/#/c/9062/

Some of the tests and infrastructure code should be compatible, and backporting them will reduce the chance of future merge conflicts, e.g. IMPALA-6405. This should not enable Decimal V2 by default.

This came out of a discussion with Alexander Behm and Tim Armstrong.
