Zoltan Haindrich commented on HIVE-21304:
-----------------------------------------
[~djaiswal]: I think around the time this feature was done; it was missed in
the review process...
moving it to the desc already started fixing some issues: (originally there was
-1 and now it uses version 2 somehow)
however...since a qtest seemingly regressed(infer_bucket_sort_num_buckets) I'll
take a closer look - but we most probably have other issues as well; because
there are a bunch of clone() methods in some Desc-s which may or may not work
as we expect....
I'm not sure if it's the best to populate this version infor during
"construction" can't we do this bucketVersion population on the operator tree
at some point?
because someone could "operate" the operator tree....and in that case the
bucketing version will probably not set to a correct value
