Subject [jira] [Created] (CRUNCH-371) AvroPathPerKeyTarget doesn't work with empty input
Date Sat, 29 Mar 2014 12:07:14 GMT
Gabriel Reid created CRUNCH-371:

             Summary: AvroPathPerKeyTarget doesn't work with empty input
                 Key: CRUNCH-371
             Project: Crunch
          Issue Type: Bug
            Reporter: Gabriel Reid

The AvroPathPerKeyTarget doesn't work properly when there is nothing to be output (for example,
if all records have been filtered out somehow). This situation results in an exception like
the following on HDFS on hadoop-1 
{code} java.lang.IllegalArgumentException: Reducer output
name 'out0' cannot be parsed
and an FileNotFoundException on hadoop-2.

In both cases, there should be no exception, and no output should be written. More background
on this in the following mailing list discussion:
