Subject [jira] [Commented] (HADOOP-11565) Add --slaves shell option
Date Thu, 12 Feb 2015 01:31:13 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11565?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14317353#comment-14317353
] 

Allen Wittenauer commented on HADOOP-11565:
-------------------------------------------

I'll admit I'm not happy with --slaves.  I was originally going to go with --batch or --batchmode.

--hosts-file is bad because we already have --hosts and --hostnames (those were inherited
from all the way back in 0.x days....)

Let me think about --slaves-file.

Thanks

> Add a --slaves shell option to hadoop-config.sh to trigger the given command on slave
nodes.  This is required to deprecate hadoop-daemons.sh and yarn-daemons.sh.
