             Summary: Add support for HDFS directory with erasure code policy 
to TeraGen and TeraSort
                 Key: MAPREDUCE-6780
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6780
             Project: Hadoop Map/Reduce
          Issue Type: Task
            Reporter: SammiChen
            Assignee: SammiChen


So far, HDFS files with erasure code policy doesn't support hflush and hsync. 
To support writing files erasure code policy, this is going to add an new 
option to choose whether hflush and hsync should be used or not when write data 
in TeraGen and TeraSort.
