Subject [jira] [Created] (HDFS-2732) Add support for the standby in the bin scripts
Date Fri, 30 Dec 2011 00:49:30 GMT
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).
