Subject [jira] Commented: (HDFS-1547) Improve decommission mechanism
Date Mon, 20 Dec 2010 23:07:01 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12973403#action_12973403
] 

Todd Lipcon commented on HDFS-1547:
-----------------------------------

One thing I've thought about a few times that I think should be considered: rather than having
separate include/exclude/decom files, why not have one file with a very simple .properties
style format?
{code}
dn1 = active
dn2 = active
dn3 = decomission
dn4 = exclude
{code}

This way we don't have to enumerate all the combinatorics like "what if it's in both include
and exclude? what if it's in decomission but not include?"

> Current decommission mechanism driven using exclude file has several issues. This bug
proposes some changes in the mechanism for better manageability. See the proposal in the next
