Ankit Singhal updated HIVE-18872:
---------------------------------
Description: Projections are not pushed down properly during getSplit()
when the query involves multiple tables although they are getting properly
pushed during getRecordReader when the task is working on the split. Due to
this , storage handler relying on projections for building query while
generating input splits are not working. (was: Projections are not pushed down
properly during getSplit() when the query involves multiple table although they
are getting properly pushed during getRecordReader when the task is working on
the split.)
