             Summary: Let JHS support different file systems for intermediate_done and done
                 Key: MAPREDUCE-6988
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6988
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobhistoryserver
            Reporter: Johan Gustavsson
            Priority: Minor


Currently JHS uses filecontext to move files from intermediate_done to done folder. Since filecontext limits the use to 1 filesystem it makes it harder to use s3 as a storage for jhist files. By moving this to filesystem interface we can set hdfs for intermediate storage and s3 as long term storage therefore reducing the number of puts to s3 and removing the need for all M/R containers to carry a s3 sdk.
