Date Wed, 09 Jul 2008 20:53:31 GMT

---------------------------------------------------------------

The patch doesn't apply to 0.18, the test case passes without the change to PipeMapRed, and
the code doesn't seem to have the problem this fixes. Does this only apply to trunk?

    This is not in 0.18

> Sometimes, finding field separator position in the input line for streaming fails with
following exception:
> org.apache.hadoop.streaming.PipeMapRed: java.lang.IllegalArgumentException: splitPos
must be in the range [0, 17]: 74
> 	at org.apache.hadoop.streaming.UTF8ByteArrayUtils.splitKeyVal(UTF8ByteArrayUtils.java:152)
