Romain Rigaux commented on HDFS-3491:
-------------------------------------

This is still broken. Octal is correctly accepted but not applied when during a MKDIR:

romain@runreal:~/projects/hue$ curl -X PUT "http://localhost:14000/webhdfs/v1/tmp/test-perm-httpfs?permission=01777&op=MKDIRS&user.name=hue&doas=hue"
{"boolean":true}
romain@runreal:~/projects/hue$ curl "http://localhost:14000/webhdfs/v1/tmp/test-perm-httpfs?op=GETFILESTATUS&user.name=hue&doas=hue"
{"FileStatus":{"pathSuffix":"","type":"DIRECTORY","length":0,"owner":"hue","group":"supergroup","permission":"755","accessTime":0,"modificationTime":1345658456869,"blockSize":0,"replication":0}}

> HttpFs seems to have these problems:
