Subject [jira] Created: (HBASE-1445) Add the ability to start a master from any machine
Date Thu, 21 May 2009 21:17:45 GMT
Add the ability to start a master from any machine
--------------------------------------------------

                 Key: HBASE-1445
                 URL: https://issues.apache.org/jira/browse/HBASE-1445
             Project: Hadoop HBase
          Issue Type: Improvement
            Reporter: Jean-Daniel Cryans
            Assignee: Jean-Daniel Cryans
            Priority: Critical
             Fix For: 0.20.0


Currently when we start a master it reads the MASTER_HOST_NAME and MASTER_ADDRESS configurations.
That means that when you want to start a master on another machine, you have to change hbase-site.xml

One thing we could do is when you want a 1 ZK, 1 Master setup, you set that value and everything
is taken care of (easier for newcomers). When you want multiple masters, you have to use a
quorum and set the hbase.regionserver.dns.interface and hbase.regionserver.dns.nameserver
configurations to bind on the right interface. Maybe those should have a different name tho.
