Gratuitous use of CHMOD in windows
Steve Lewis 2011-11-21, 23:47
I am running a job on a cluster launching from a windows box and "
fs.default.name" to point the job to the cluster.
Everything works until the last step where I say

FileSystem fileSystem = FileSystem.get(config); // this is hdfs
fileSystem.copyToLocalFile(src, dst); // local system

at this point RawLocalFileSystem tries to exec chmod which is not on

This looks like a bug - it seems that there should be a fallback system or
better yet a call to the
Java standard File.canWrite command before attempting to alter permissions
