Date Wed, 17 Oct 2012 05:06:02 GMT
Sameer Vaishampayan created HADOOP-8937:
-------------------------------------------

             Summary: ClientProtocol should support a way to get DataNodeInfo for a particular
data node.
                 Key: HADOOP-8937
                 URL: https://issues.apache.org/jira/browse/HADOOP-8937
             Project: Hadoop Common
          Issue Type: Improvement
          Components: fs
    Affects Versions: 1.0.3
            Reporter: Sameer Vaishampayan
            Priority: Minor
             Fix For: 2.0.3-alpha


HBase project needs a way to find if a DataNode is running local or not on a given host. The
current way is too expensive in which getDatanodeReport needs to be called which returns information
for all data nodes in the cluster.
