[jira] [Created] (HIVE-9731) WebHCat MapReduce Streaming Job does not allow StreamXmlRecordReader to be specified

Hari Sankar Sivarama Subramaniyan created HIVE-9731:
-------------------------------------------------------

             Summary: WebHCat MapReduce Streaming Job does not allow StreamXmlRecordReader to be specified
                 Key: HIVE-9731
                 URL: https://issues.apache.org/jira/browse/HIVE-9731
             Project: Hive
          Issue Type: Bug
          Components: WebHCat
            Reporter: Hari Sankar Sivarama Subramaniyan
            Assignee: Hari Sankar Sivarama Subramaniyan


Hadoop Streaming allows -inputreader parameter to specify use of StreamXmlRecorderReader
(example)
hadoop jar hadoop-streaming-2.5.1.jar \
-inputreader "StreamXmlRecord,begin=BEGIN_STRING,end=END_STRING" \
(rest of the command)
WebHCat's StreamingDelegator does not include -inputreader as a valid option when submitting jobs to http://www.myserver.com/templeton/v1/mapreduce/streaming endpoint. If -inputreader is specified and passed to templeton server (perhaps via CURL operation) , it will get truncated and not passed as parameter from TempletonControllerJob to Hadoop.
