IP tables

IP tables

Rising Star

For locking down the hadoop cluster the usual recommendation is to set up Sentry and turn on firewalls (remember, during installation and setup the firewalls should be turned off - this is a recommendation from Cloudera).

But when it comes to a lock down, meaning the firewall configuration, it is really hard to figure out, what communication (protocol/port) should and what communications should not allowed on the nodes.


It would be nice to have a new feature in Cloudera Manager with a wizard for the definition of IP tables.


I think we are not alone with this  request/suggestion
