> 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.
