Description

Observed an issue with customer case where there are 2 buckets (bucket_00000 and bucket_00001).
Based bucket 0 had some rows whereas bucket 1 was empty.
Delta bucket 0 and 1 had some rows.

ETL split strategy did not generate OrcSplit for bucket 1 even though it had some rows in delta directories.
