I can see in my MR jobs that the ports being used vary from sth like 36000 up to 45000. Is this configurable anywhere in Ambari? I am currently playing with ambari with datanodes running on vagrant vms, I need to setup ports forwarding.. </P> Thu, 15 Feb 2018 05:51:53 GMT solinski_a 2018-02-15T05:51:53Z https://community.cloudera.com/t5/Archives-of-Support-Questions/IPC-Server-ports-how-to-set-the-range/m-p/218644#M74583 <P>Is it possible to set range of IPC Server listener ports?

You can refer to the details directly here: <A href="https://hadoop.apache.org/docs/r2.7.3/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml" target="_blank">https://hadoop.apache.org/docs/r2.7.3/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml</A></P> Thu, 15 Feb 2018 06:55:12 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/IPC-Server-ports-how-to-set-the-range/m-p/218645#M74584 solinski_a 2018-02-15T06:55:12Z
