Subject [jira] [Commented] (HDFS-3912) Detecting and avoiding stale datanodes for writing
Date Wed, 03 Oct 2012 13:00:11 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3912?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13468542#comment-13468542

nkeywal commented on HDFS-3912:
-------------------------------
