Subject [jira] [Commented] (HDFS-2391) Newly set BalancerBandwidth value is not displayed anywhere
Date Thu, 10 May 2012 16:00:52 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2391?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13272439#comment-13272439
] 

Harsh J commented on HDFS-2391:
-------------------------------

bq.   -1 tests included.  The patch doesn't appear to include any new or modified tests.

Logging additions, does not require tests. Did however run HDFS manually to verify the INFO
log printed upon setting a new balancer bandwidth value.
