Vinayakumar B created HDFS-6995: ----------------------------------- Summary: Block should be placed in the client's 'rack-local' node if 'client-local' node is not available Key: HDFS-6995 URL: https://issues.apache.org/jira/browse/HDFS-6995 Project: Hadoop HDFS Issue Type: Bug Components: namenode Reporter: Vinayakumar B Assignee: Vinayakumar B
HDFS cluster is rack aware. Client is in different node than of datanode, but Same rack contains one or more datanodes. In this case first preference should be given to select 'rack-local' node. Currently, since no Node in clusterMap corresponds to client's location, blockplacement policy choosing a *random* node as local node and proceeding for further placements. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
