Review request for Ambari, Andrew Onischuk, Sumit Mohanty, and Vitalyi
Brodetskyi.
Bugs: AMBARI-15506
https://issues.apache.org/jira/browse/AMBARI-15506
Repository: ambari
Description
-------
Currently Ambari does not support the definition of multiple Nameservices. It
is always assumed hdfs_site['dfs.nameservices'] is just a string defining one
nameservice.
Multiple nameservices can be configured for exmaple to support seamless distcp
between two HA clusters. The nameservices are defined as a comma separated list
in hdfs_site['dfs.nameservices'].
This patch introduces the method get_nameservice(hdfs_site), which splits the
value into in an array and identifies the nameservice for the current cluster
with what is set in hdfs_site['dfs.namenode.shared.edits.dir']. By default the
first nameservice is returned or empty.
To verify the current namservice it would be preferred to use fs.defaultFS in
core-site, but getting this config into namenode_ha_utils.py seems more
involved.
