Ports Used for Secure Services

This section lists the ports used by web interfaces for secure Hadoop 2 services

The MapR software supports Hadoop 2 services built on the YARN framework. While Hadoop 1 services such as JobTracker and TaskTracker use the same ports for the HTTP and HTTPS protocols, the Hadoop 2 services use different ports, listed in the following table:

Service HTTP (non-secure) port HTTPS (secure) port
NodeManager 8042 8044
ResourceManager 8088 8090
HistoryServer 19888 19890
Note: For a list of all ports used by MapR, see Ports Used by MapR.
