Andrew Wang commented on HDFS-6434:
-----------------------------------
Hmm, so I dug in a little more to this issue, and noticed HADOOP-9155. It looks
like the default permissions are supposed to be 0777 for dirs and 0666 for
files, and WebHdfsFileSystem is unfortunately not using the new FsPermission
methods that were introduced. The default umask of 0022 at
{{CommonConfigurationKeys.FS_PERMISSIONS_UMASK_DEFAULT}} is what then brings it
down to to 0755 or 0644.
So, is the right fix here to use the new FsPermission methods, i.e.
getDirDefault and getFileDefault? I think we can just call this one a bug,
given that the behavior in HADOOP-9155 is the expected one.
