Is there a fix to this yet? I am facing a similar issue

> Feature added by this Jira has a problem while setting up some of the invalid xml characters e.g. ctrl-A e.g. mapred.textoutputformat.separator = "\u0001"
> e,g,
> String delim = "\u0001";
> Conf.set("mapred.textoutputformat.separator", delim);
> Job client serializes the jobconf with mapred.textoutputformat.separator set to "\u0001" (ctrl-A) and problem happens when it is de-serialized (read back) by job tracker, where it encounters invalid xml character.
> The test for this feature public : testFormatWithCustomSeparator() does not serialize the jobconf after adding the separator as ctrl-A and hence does not detect the specific problem.
> Here is an exception:
> 08/12/06 01:40:50 INFO mapred.FileInputFormat: Total input paths to process : 1
> org.apache.hadoop.ipc.RemoteException: java.io.IOException:
