> If a table is bucketed, `OpTraitsRulesProcFactory::TableScanRule` ends up
> verifying if the partitions have got the same number of files as the number
> of buckets in table.
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/metainfo/annotation/OpTraitsRulesProcFactory.java#L185
> In large tables, this turns out to be very time consuming (100s of seconds)
> operation. It would be good to have an option to by pass this depending on
> need basis.
