It turned out it was repeatingly asking Namenode for a partial block list of one datanode, which was done while the balancer was running. > NameNode should notify Balancer that the datanode is not available and Balancer should stop asking for the datanode's block list. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
