Philip Su commented on MAPREDUCE-3638:
--------------------------------------
I did some more follow up testing on this and I think I know more precisely
where the problem is.
1) The failure occurs when running a streaming job with the -cacheFile option
on a local file system using file:///<path>.
2) I ran hdfs dfs -ls file:///<path> to make sure the file exists.
3) I ran the same streaming job using the same value from 1). But instead of
using the deprecated -cacheFile option, I used -files instead. The job ran and
passed.
So is seems when running the streaming job using the deprecated option
-cacheFile on a local file system, it is not getting the correct file
permission on it.
