Opening port 8021 in Red Hat Linux

Question

I am trying to load data into hive server through a java client, but its throwing exception while loading the data, on checking the hive log I found out the issue is arising because port 8021 is not open. Is there anyway to open the 8021 port, I have the root permission for the system. Thanks

You might need to use iptables command as follows:

iptables -I INPUT -p tcp -m tcp --dport 8021 -j ACCEPT

To save the rule, you also need to issue this:

sudo service iptables save
