> With HIVE-3976, the maximum precision is set to 65, and maximum scale is to
> 30. After discussing with several folks in the community, it's determined
> that 38 as a maximum for both precision and scale are probably sufficient, in
> addition to the potential performance boost that might become possible to
> some implementation.
> This task is to make such a change. The change is expected to be trivial, but
> it may impact many test cases. The reason for a separate JIRA is that patch
> in HIVE-3976 is already in a good shape. Rather than destabilizing a bigger
> patch, a dedicate patch will facilitates both reviews.
> The wiki document will be updated shortly.
