Subject [jira] Created: (HDFS-1293) Allow dfs.balance.bandwidthPerSec to be specified at invocation time for balancer
Date Fri, 09 Jul 2010 14:07:52 GMT
Allow dfs.balance.bandwidthPerSec to be specified at invocation time for balancer
---------------------------------------------------------------------------------

                 Key: HDFS-1293
                 URL: https://issues.apache.org/jira/browse/HDFS-1293
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: balancer
            Reporter: Patrick Angeles


The dfs.balance.bandwidthPerSec parameter is read at Datanode start time. It would be nice
to allow this parameter to be passed in when the balancer is invoked so, for example, it can
be run during off-peak hours with a higher bandwidth setting.
