FAQ
The webui of namenode should include Rack column in the live datanodes table
----------------------------------------------------------------------------

Key: HDFS-1090
URL: https://issues.apache.org/jira/browse/HDFS-1090
Project: Hadoop HDFS
Issue Type: Improvement
Components: name-node
Reporter: luoli


It is a great feature that hadoop support rack-aware, but in the default webui of namenode, their is no column in the live datanodes table to show what rack the datanode belongs to. This is not convenient for a cluster which has configed the rack info of the cluster. This can solve easily, just add it in the dfshealth.jsp, and also for the convenient of sort the live datanode table on the column of rack, we can just add it in the JspHelper.java.
