> 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.
