Arpit Agarwal commented on HDFS-6441: ------------------------------------- Benoy, couple of minor issues with your latest patch. # We should not allow -include and -exclude in the same invocation. # Nitpick: BalancerUtil can be a static nested class in Balancer. +1 with these fixed. Thanks for incorporating the changes from HDFS-6010. > Add ability to exclude/include few datanodes while balancing > ------------------------------------------------------------ > > Key: HDFS-6441 > URL: https://issues.apache.org/jira/browse/HDFS-6441 > Project: Hadoop HDFS > Issue Type: Improvement > Components: balancer > Affects Versions: 2.4.0 > Reporter: Benoy Antony > Assignee: Benoy Antony > Attachments: HDFS-6441.patch, HDFS-6441.patch, HDFS-6441.patch, > HDFS-6441.patch, HDFS-6441.patch, HDFS-6441.patch, HDFS-6441.patch, > HDFS-6441.patch, HDFS-6441.patch, HDFS-6441.patch, HDFS-6441.patch, > HDFS-6441.patch, HDFS-6441.patch > > > In some use cases, it is desirable to ignore a few data nodes while > balancing. The administrator should be able to specify a list of data nodes > in a file similar to the hosts file and the balancer should ignore these data > nodes while balancing so that no blocks are added/removed on these nodes. > Similarly it will be beneficial to specify that only a particular list of > datanodes should be considered for balancing. -- This message was sent by Atlassian JIRA (v6.2#6252)
