Subject [jira] [Commented] (HDFS-7961) Trigger full block report after hot swapping disk
Date Fri, 20 Mar 2015 02:11:39 GMT

    [ https://issues.apache.org/jira/browse/HDFS-7961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14370569#comment-14370569
] 

Colin Patrick McCabe commented on HDFS-7961:
--------------------------------------------

maybe {{testFullBlockReportAfterHotSwappingVolumes}} should be named something like {{testFullBlockReportAfterRemovingVolumesViaHotSwap}}
?

rest of the patch looks good.  +1 pending jenkins.

> DN should trigger a full block report immediately after running hot swapping drives.
