      Description

      This is an umbrella JIRA to collect issues related to the support of multiple Nameservices.

      Currently all implementations in Amabari assume that hdfs_site['dfs.nameservices'] is just a string defining one nameservice, while it actually defines multiple nameservices.

      Multiple nameservices can be configured for exmaple to support seamless distcp between two HA clusters.

      At least 3 issues can be experienced:

      1. Restart fails, because HdfsResource does not work, related to namenode_ha_utils.py
      2. (Blueprint) Install fails because DN's register with wrong cluster. How do DN pick the right Nameservice?
      3. Alerting is broken because it configures namservices as being one nameservice
