--------------------------------------------

             Summary: HIVE-17562 is returning incorrect results
                 Key: HIVE-17705
                 URL: https://issues.apache.org/jira/browse/HIVE-17705
             Project: Hive
          Issue Type: Bug
          Components: Transactions
    Affects Versions: 3.0.0, 2.4.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran
            Priority: Blocker


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.
