|---|---|
Scripts maintain the same status in the Ambari Views Framework as they had in Hue. The Hue-to-Views Migration tool does not validate scripts. Some hive queries (mysql version 0.4.0) may fail to migrate, and cause the Hue-to-Views migration to stop. The Hue-to-Views migration tool does not support HA. You must provide the current, active namenode for the target cluster regarding the Webhdfs URI for Ambari. |
