Hi, I am having problem in reduce if the firewall is enabled.
I am using default settings from hadoop-default.xml and hadoop-site.xml And I just changed this port number <name>mapred.task.tracker.report.address</name> <!--<value>127.0.0.1:50024</value>--> I created the firewall rule to allow port range 50000:50100 between the slaves and master. But reduce on the slaves using some other ports seems. So Reduce always hangs with firewall enabled. If I disable the firewall it works fine. Could you please let me know what I am missing or where to control the hadoop random port creation? Thanks, Senthil
