Description

I run a streaming job with a Ctrl-A character in the command line option as follows:

$HSTREAMING -mapper "/bin/sort -t'^A'" -input "input/*" -output output

It causes a exeception as listed below. If i run the same command without the Ctrl-A character the command completes successfully.

Exception in thread "main" org.apache.hadoop.ipc.RemoteException: java.io.IOException: java.lang.RuntimeException: org.xml.sax.SAXParseException: Character reference "&#1" is an invalid XML character.
