Gaurav Nagar updated AMBARI-14212:
----------------------------------
Description: Connections in different views are cached in the ViewContext,
through the UserLocal objects of the respective views. However, on update of
configuration parameters of the view instance, the connection for the instance
in the UserLocal object is not refreshed. This causes a failure in connection
to the new/updated data node. The solution to this is the drop the instance
specific connection and on new request from the browser , re-establish the
connection with the data node, and update the UserLocal objects.
> Changes in Instance Definition does not get reflects in pig and hive view due
> to caching in UserLocal.java
