> 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.
