Subject Hadoop Port Configuration
Date Mon, 31 Mar 2008 21:00:03 GMT

I am using default settings from hadoop-default.xml and hadoop-site.xml

And I just changed this port number



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
