Subject [jira] [Created] (HDFS-3226) Allow GetConf tool to print arbitrary keys
Date Fri, 06 Apr 2012 21:13:22 GMT
Allow GetConf tool to print arbitrary keys
------------------------------------------

                 Key: HDFS-3226
                 URL: https://issues.apache.org/jira/browse/HDFS-3226
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: tools
    Affects Versions: 2.0.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon


Currently the "hdfs getconf" tool can only print out certain keys, like the list of NNs, etc.
It would be handy to allow it to fetch an arbitrary configuration. For example, users may
wish to write shell scripts that interact with their hadoop cluster, and it is useful to be
able to fetch configs like the name of the superuser, or the state of whether HA is enabled.
