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

             Summary: OrcFileMergeOperator does not use correct compression 
buffer size
                 Key: HIVE-12450
                 URL: https://issues.apache.org/jira/browse/HIVE-12450
             Project: Hive
          Issue Type: Bug
    Affects Versions: 1.2.1, 1.2.0, 1.3.0, 2.0.0
            Reporter: Prasanth Jayachandran
            Assignee: Prasanth Jayachandran


OrcFileMergeOperator checks for compatibility before merging orc files. This 
compatibility check include checking compression buffer size. But the output 
file that is created does not honor the compression buffer size and always 
defaults to 256KB. This will not be a problem when reading the orc file but can 
create unwanted memory pressure because of wasted space within compression 
buffer.
