------------------------------------------
Summary: Balancer should work with ObserverNode
Key: HDFS-14162
URL: https://issues.apache.org/jira/browse/HDFS-14162
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Konstantin Shvachko
Balancer provides a substantial RPC load on NameNode. It would be good to
divert Balancer RPCs {{getBlocks()}}, etc. to ObserverNode. The main problem is
that Balancer uses {{NamenodeProtocol}}, while ORPP currently supports only
{{ClientProtocol}}.
