[jira] [Created] (HADOOP-10138) Support custom record separator with streaming

Christopher Auston created HADOOP-10138:
-------------------------------------------

             Summary: Support custom record separator with streaming
                 Key: HADOOP-10138
                 URL: https://issues.apache.org/jira/browse/HADOOP-10138
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Christopher Auston
            Priority: Minor


We store XML documents in sequence files as values.  The values may contain newlines.  It is useful to have hadoop-streaming output a zero-byte instead of a newline to delimit key-value boundaries.  The mapping script can then find the key-value pairs unambiguously by looking for zero-bytes.
I find this really useful so I can use a ruby script for quick adhoc queries.
I have a patch with unit test that I will attach.
