Balu Vellanki updated FALCON-1648:
----------------------------------
    Description: 
Today, when specifying a cluster entity, user should create three dirs in HDFS 
with proper permissions.
1. staging
2. tmp
3. working

We can simplify this by letting user specify a single location, i.e. staging. 
The working dir will be created by falcon under <staging_dir>/working. The tmp 
dir will be <staging_dir>/tmp. User can still overwrite these values in the 
cluster.xml, this way the cluster definition is backwards compatible. 

Falcon-817 was supposed to address this issue. But when I submit a cluster 
entity without working and temp locations, the submission fails with following 
error.
