> UI and agent code is using namenode configuration as a validation to check if 
> HDFS is selected or not and perform some HDFS specific operations like 
> creating /tmp directory, reading hadoop-env configurations like 
> hdfs_log_dir_prefix, dropping fast-hdfs-resource.jar etc., because of which 
> the configurations defined for HCFS types are not getting populated. The 
> ambari server component should tarverse thhrough the stack configuration and 
> populate (hadoop-env or cluster-env) dictionary if HCFS file system is 
> asscoated as part of the stack. The dictionary configuration should be used 
> in UI and agent code to allow FS operations require to bootstrap the cluster 
> deployment.
