fencing method should be able to be configured on a per-NN or per-NS basis
--------------------------------------------------------------------------
Key: HADOOP-8077
URL: https://issues.apache.org/jira/browse/HADOOP-8077
Project: Hadoop Common
Issue Type: Sub-task
Components: ha
Affects Versions: HA Branch (HDFS-1623)
Reporter: Todd Lipcon
Currently, the fencing method configuration is global. Given that different
nameservices may use different underlying storage mechanisms or different types
of PDUs, it would be preferable to allow the fencing method configuration to be
scoped by namenode or nameservice.
