      Description

      After CDAP has been installed on a Hadoop cluster, the Hadoop cluster can be upgraded to HA cluster. When the cluster becomes HA certain things change, and CDAP will have to handle the changes.

      For example HDFS URLs will no longer have namenode hostname, instead the URL will now contain logical namenode name. In CDAP we store HDFS URLs in some places like co-processor names, log file names, and Fileset names . We'll need to migrate all these into logical names.
