Subject [jira] [Commented] (HDFS-7411) Refactor and improve decommissioning logic into DecommissionManager
Date Tue, 10 Feb 2015 22:31:12 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14315092#comment-14315092

Chris Douglas commented on HDFS-7411:
-------------------------------------

bq. What if there is a bug you don't know how to fix?
Heh; I don't think you intended to float this as a precondition for commit.

[~szetszwo], the patch has received a fair amount of review. Are there cases that should be
tested that would increase your confidence in its correctness and performance? Per your example,
are there additional parameters that should be added to the algorithm?
