Summary: Add ability to Ignore 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
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.
