Subject [jira] [Commented] (HDFS-9043) Doc updation for commands in HDFS Federation
Date Mon, 14 Sep 2015 06:02:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9043?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14742983#comment-14742983
] 

J.Andreina commented on HDFS-9043:
----------------------------------

Thanks [~aw] for the comments.

bq. The given trunk patch appears to be missing the same fixes as the branch-2 patch
In trunk already command is updated correctly using hdfs as :
{noformat}
[hdfs]$ $HADOOP_PREFIX/bin/hdfs --daemon start balancer [-policy <policy>]
{noformat}

bq.  Also, if we're going to bother with this, let's make it complete: all of the sbin commands
should get replaced with their equivalent bin versions since sbin is mostly deprecated.

Currently the sbin commands used are :
{noformat}
sbin/refresh-namenodes.sh
sbin/distribute-exclude.sh
sbin/stop-dfs.sh
sbin/start-dfs.sh
{noformat}
And for above commands there is no alternative yet. 

Please correct me if iam wrong .

complete command usage, see balancer.
