Mark Grover commented on HIVE-3403:
-----------------------------------
Sorry for joining the party a little late.
Just a thought: we already have a property hive.optimize.bucketmapjoin that
deals with the same question - whether or not to use BucketizedHiveInputFormat.
Would it make sense to use the same property? I would go as far as saying, most
people who would want to auto-convert their joins to bucketed joins would be
interested in converting their joins to sort-merge bucketed joins (if data is
sorted per join keys).
What do you think?
> user should not specify mapjoin to perform sort-merge bucketed join
