Summary: Support for Multiple Nameservices
Key: AMBARI-15507
URL: https://issues.apache.org/jira/browse/AMBARI-15507
Project: Ambari
Issue Type: Bug
Affects Versions: trunk
Reporter: Henning Kropp
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 nameservices,
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:
# Restart fails, because HdfsResource does not work, related to
namenode_ha_utils.py
# (Blueprint) Install fails because DN's register with wrong cluster. Who do DN
pick the right Nameservice?
# Alerting is broken because it configures namservices as being one nameservice
