Prasanth Jayachandran commented on HIVE-17705:
----------------------------------------------
This patch does the following
1) If base file has no stripes, treat it as orc split with start = 0, length =
file length (this is how BI creates splits - entire file becomes a split).
2) As a result of 1) we no longer access covered array. No longer will throw
ArrayIndexOutOfBounds
> HIVE-17562 is returning incorrect results

> HIVE-17562 is generating incorrect results intermittently. Also derived
> tables with default file format set to ORC is resulting in AIOB exception.
> 1) Intermittent issue happens based on the order of selection of bucket file
> for ETL split strategy. Flipping the covered boolean flag looks error prone.
> The test case always passed when bucket_00000 is analyzed first. When
> bucket_00001 is analyzed first duplicate rows were generated.
> 2) Some internal test revealed a test failure with ArrayIndexOutOfBounds
> exception which happens for non-bucketed table.
