Ashutosh Chauhan commented on HIVE-3403:
----------------------------------------
Make sense. I am not suggesting to include all that in this jira, but wanted to
make sure we are on same page as to where are heading.
Though, w.r.t, configs I can see your point about adding more configs, but I
still think by default optimization configs should be on. Whole point of
release is to ship stable codebase. By definition trunk is not considered
stable (as stable as in making release out of it), so time we get between
committing to trunk and releasing is for stablizing new codebase, but if by
default configs are off, bugs lurking in new codebase will never be exposed.

> to set hive.optimize.bucketmapjoin.sortedmerge to true, and also specify the
> mapjoin hint.
> The user should not specify any hints.
