Hadoop’s namenode and datanodes expose a bunch of TCP ports used by Hadoop’s daemons to communicate to each other or listen directly to users’ requests. These ports information are needed by both the Hadoop users and cluster administrators to write programs or configure firewalls/gateways accordingly.

    • Namenode 50070


    • Datanodes 50075


    • Secondarynamenode 50090


    • Backup/Checkpoint node 50105


    • Jobracker 50030


    • Tasktrackers 50060
