[jira] [Created] (TEZ-2377) RandomWriter ends up using TextOutputFormat instead of SequenceFileOutputFormat

Rajesh Balamohan created TEZ-2377:
-------------------------------------

             Summary: RandomWriter ends up using TextOutputFormat instead of SequenceFileOutputFormat
                 Key: TEZ-2377
                 URL: https://issues.apache.org/jira/browse/TEZ-2377
             Project: Apache Tez
          Issue Type: Bug
            Reporter: Rajesh Balamohan
            Assignee: Rajesh Balamohan


{code}
yarn jar ./dist/tez/tez-tests-0.7.0-SNAPSHOT.jar randomwriter "-Dmapreduce.randomwriter.totalbytes=10737418" /tmp/test1
{code}

This ends up generating TextOutputFormat.  

{code}
yarn jar ./dist/tez/tez-tests-0.7.0-SNAPSHOT.jar sort  
"-Dmapreduce.framework.name=yarn-tez" -r 5 /tmp/test1 /tmp/test_sorted
{code}

This ends up throwing error 
{noformat}
Failure while running task:java.io.IOException: hdfs://tez-vm:56565/tmp/test1/part-00000 not a SequenceFile
