Description

During Hiveserver2 start script, a directory create request is sent using the below JSON structcture but the permission request sent from fast-hdfs-resource.jar is different from the original permission (777) defined in the JSON file. It looks the mode is getting treated as Dec instead of OCT.

 {"target": "/apps/hive/warehouse", "dfs_type": "HCFS", "action": "create", "mode": "777", "owner": "hive", "type": "directory"}, 

https://github.com/apache/ambari/blob/trunk/contrib/fast-hdfs-resource/src/main/java/org/apache/ambari/fast_hdfs_resource/Resource.java#L217

To verify, if we change the json to below then we are actually getting correct permission.

{"target": "/apps/hive/warehouse", "dfs_type": "HCFS", "action": "create", "mode": "511", "owner": "hive", "type": "directory"}
