> Graceful handling of codec errors during decompression

> When using a compression codec for intermediate compression, some cases of
> corrupt data can cause the codec to throw exceptions other than IOException
> (eg java.lang.InternalError). This will currently cause the whole reduce task
> to fail, instead of simply treating it like another case of a failed fetch.
