Subject [jira] [Commented] (MAPREDUCE-5053) java.lang.InternalError from decompression codec cause reducer to fail
Date Fri, 08 Mar 2013 17:30:13 GMT

Jonathan Eagles commented on MAPREDUCE-5053:
--------------------------------------------

Minor nit. Comment about mock object return null in new test should be updated. Also, if you
can provide a 23 patch, I can check it in there also.

> lz4, snappy, zlib, and lzo Decompressor's only throw java.lang.InternalError. This exception
will cause the reducer to fail and bypass all of the fetch failure logic.  The decompressing
errors should be treated as fetch failures.
