> Unable to create feed : FilePermission error under cluster staging directory

> Submit a cluster entity as user "user1", schedule a feed entity as "user1".
> Now submit and schedule a feed entity as "user2" and feed submission can fail
> with the following error
> {code}
> Caused by:
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.security.AccessControlException):
> Permission denied: user=user2, access=WRITE,
> inode="/apps/falcon-user1/staging/falcon/workflows/feed":user1:falcon:drwxr-xr-x
> at
> org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.checkFsPermission(FSPermissionChecker.java:271)

> org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:257)
> at
> org.apache.hadoop.hdfs.server.namenode.FSPermissionChecker.check(FSPermissionChecker.java:238)
> {code}
> This is caused because Falcon creates <staging_dir>/falcon/workflows/feed and
> <staging_dir>/falcon/workflows/process only when a feed/process entity are
> scheduled. The owner of these dirs is the user scheduling the entity. The
> permissions are based on the default umask of the FS. If a new feed/process
> entity are being scheduled by a different user, things can fail.
> Solution is to make <staging_dir>/falcon/workflows/feed and
> <staging_dir>/falcon/workflows/process owned by Falcon with permissions 777.
