Subject [jira] [Commented] (HDFS-10912) Ozone:SCM: Add safe mode support to NodeManager.
Date Thu, 29 Sep 2016 17:25:20 GMT

    [ https://issues.apache.org/jira/browse/HDFS-10912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15533407#comment-15533407

Anu Engineer commented on HDFS-10912:

My options at this moment is to name this as "nonSafeSafemode" or chillMode. I think chillMode
looks better. Anyways we can always rename these modes -- Hopefully all these names are hidden
inside NodeManager so that no one really cares. So In short,  I will rename this to chill
mode for now and wait until someone tells me how badly it is named and comes up with a better
name :)

Also when we have real safe mode, that does take look at the container state, this function
would be used from that mode. So this chill mode is not going to be public.
