Hello, According to CDH documentation (http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/4.5.3/Cloudera-Manager-Enterprise-Edition-User-Guide/cmeeug_topic_5_13.html), "/" can NOT be used as mount point. Is there some explicit reason for this? Because of this limitation, if HDFS without federation has been used for a while, then user wants to enable Federation, some existing client program will be broken because "/" can't be used anymore. Thanks.
