Background

For the federate scenario of Hadoop based Router, when accessing HDFS (Hadoop based distributed file system), the client needs to respond to the client request through Router and forward the request agent to the correct NameNode (named node). If a plurality of clients access the HDFS simultaneously, the Router agent client requests the server NameNode, and an individual server NameNode is abnormal when processing the request, because the Router hides the client information from the server NameNode, the server NameNode cannot identify which client request has an error, which is not beneficial to positioning of operation abnormal failure problem and troubleshooting of network input and output blocking problem, and cannot analyze the load balance condition of the Router in the whole federal cluster, so that the federal cluster is difficult to process the error and analyze the load, and the availability is poor.
