HA: allow hdfs-specific names to be used in haadmin
---------------------------------------------------
Key: HDFS-2808
URL: https://issues.apache.org/jira/browse/HDFS-2808
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha
Affects Versions: HA branch (HDFS-1623)
Reporter: Eli Collins
Assignee: Eli Collins
Currently the HAAdmin CLI tools refer to services using host:port, would be
more user friendly to allow people to use hdfs-specific logical names, eg the
NNs configured in dfs.ha.namenodes and let it do the mapping to host:port.
Could do this by wrapping HAAdmin with a hdfs-specific class and a dfshadmin
command.
