Ravi Gummadi commented on MAPREDUCE-661:
----------------------------------------
Failed test is not related to this patch.
I don't see an easy way to add a unit test for this. Tested manually with -i
option and throwing IOException from within setup().
> distcp doesn't ignore read failures with -i in setup() before MapReduce job
> is started

> After HADOOP-3873, file checksums are checked in setup() before actual
> MapReduce job is started. And when getFileChecksum() fails with
> socketTimeoutException when called from setup(), distcp fails even though -i
> option is specified by user. Similar to how map tasks ignore read failures,
> setup() should also ignore them and continue processing remaining files.
