Subject [jira] [Commented] (HDFS-8688) replace shouldCheckForEnoughRacks with hasClusterEverBeenMultiRack
Date Fri, 17 Jul 2015 02:27:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14630680#comment-14630680
] 

Walter Su commented on HDFS-8688:
---------------------------------

bq. So in the case all replicas are in decommission_inprogress state, blockHasEnoughRacks
might still be called. If so, blockHasEnoughRacks currently returns false as it couldn't find
any live replica; but with the patch, it returns true.
Oh, I see. You are right. Thanks for the explanation.
