Add support for the standby in the bin scripts
----------------------------------------------
Key: HDFS-2732
URL: https://issues.apache.org/jira/browse/HDFS-2732
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha
Affects Versions: HA branch (HDFS-1623)
Reporter: Eli Collins
Assignee: Eli Collins
We need to update the bin scripts to support SBNs. Two ideas:
Modify start-dfs.sh to start another copy of the NN if HA is configured. We
could introduce a file similar to masters (2NN hosts) called standbys which
lists the SBN hosts, and start-dfs.sh would automatically make the NN it starts
active (and leave the NNs listed in standby as is).
Or simpler, we could just provide a start-namenode.sh script that a user can
run to start the SBN on another host themselves. The user would manually tell
the other NN to be active via HAAdmin (or start-dfs.sh could do that
automatically, ie assume the NN it starts should be the primary).
