Subject [jira] [Created] (HBASE-10139) Regionserver should listen on all network interfaces
Date Thu, 12 Dec 2013 05:20:10 GMT
Rural Hunter created HBASE-10139:
------------------------------------

             Summary: Regionserver should listen on all network interfaces
                 Key: HBASE-10139
                 URL: https://issues.apache.org/jira/browse/HBASE-10139
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.96.0
            Reporter: Rural Hunter
            Priority: Critical


My hbase cluster is running in LAN network. All master and slaves hostnames are resolved to
LAN ip
like this:
master 192.168.1.2
slave1 192.168.1.3
slave2 192.168.1.4
...
I found some hbase ports are listening on LAN port only for example the region server:
tcp6 0 0 192.168.1.3:60020 :::* LISTEN

while zookeeper is listening on all network interfaces:
tcp6 0 0 :::2181 :::* LISTEN 

So in this case, although all the servers have WAN ips, It is still impossible
for the client in WAN to access hbase cluster even I can configure the client to resolve all
host names to WAN ip. I think region server should listen on all network interfaces like the
zookeeper does.
