Hi, I am playing with CDH5 jobtracker HA and YARN HA configuration.
I am wondering about the configuration example in their web site. http://www.cloudera.com/content/cloudera-content/cloudera-docs/CDH5/latest/CDH5-High-Availability-Guide/cdh5hag_jt_ha_config.html They uses for each service on different nodes different ports. Like mapred.jobtracker.rpc-address.logicaljt.jt1 = myjt1.myco.com:8021 mapred.jobtracker.rpc-address.logicaljt.jt2 = myjt2.myco.com:8022 mapred.job.tracker.http.address.logicaljt.jt1 = 0.0.0.0:50030 mapred.job.tracker.http.address.logicaljt.jt2 = 0.0.0.0:50031 mapred.ha.jobtracker.rpc-address.logicaljt.jt1 = myjt1.myco.com:8023 mapred.ha.jobtracker.rpc-address.logicaljt.jt2 = myjt2.myco.com:8024 mapred.ha.jobtracker.http-redirect-address.logicaljt.jt1 = myjt1.myco.com:50030 mapred.ha.jobtracker.http-redirect-address.logicaljt.jt2 = myjt2.myco.com:50031 Why do I need different ports when i use different nodes? On their web site about YARN HA they write >> "In an HA setting, you should configure two RMs to use different ports (for >> example, ports on different hosts)." But in the example they use the same ports for the 2 ressource managers. So do I need to use different ports on different nodes? Regards Hansi
