Hi, akshay Seems it’s not distcp’s business, SocketTimeout exceptions may be caused by network unreachable or unavailable remote server, you can communicate with the target hdfs cluster directly on the machine you executed distcp command to have a test. Fully causes and suggestions given by community can be fetched from here: https://wiki.apache.org/hadoop/SocketTimeout <https://wiki.apache.org/hadoop/SocketTimeout>
There is a doubt in your distcp command, why using port 50070 (http port) instead of 8020 (rpc port) for the target hdfs cluster? I’m confusing that it still can connect with 8020 according to your logs.
