HBase cluster replication firewall rules

[Levy Meny <Me...@comverse.com>]

Hi,
We are using HBase replication (over Apache 0.94.2) between two sites and we need to define firewall rules between the two sites.
Can anyone provide some information regarding the ports that are used between the sites?

Our understand is:
Replication is from site1  to site2.

*         Region Server (site1) to Region Server (site2), port 60020

*         Region Server (site1) to ZooKeeper (site2), port 2181

*         ZooKeeper (site1) to ZooKeeper (site2) Which of the following ports do we need: 2181, 2888, 3888?

Also, what protocol is used (is IPC simple generic TCP?)

Thanks,

Meny Levy
