Mit Desai commented on HDFS-742: -------------------------------- Hey [~hairong], are you still working on this JIRA? If not, I can take it over and work on it. > A down DataNode makes Balancer to hang on repeatingly asking NameNode its > partial block list > -------------------------------------------------------------------------------------------- > > Key: HDFS-742 > URL: https://issues.apache.org/jira/browse/HDFS-742 > Project: Hadoop HDFS > Issue Type: Bug > Components: balancer > Reporter: Hairong Kuang > Assignee: Hairong Kuang > > We had a balancer that had not made any progress for a long time. 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 (v6.2#6252)
