Subject [jira] [Commented] (HBASE-5353) HA/Distributed HMaster via RegionServers
Date Wed, 08 Feb 2012 22:00:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204043#comment-13204043

Jesse Yates commented on HBASE-5353:
------------------------------------

bq. have failover support for the master,

oh right. But this means you don't need to worry about where you run your master - the system
takes care of all of that for you, making the startup process easier. Works well here b/c
we have the master down to such a lightweight process.

> Currently, the HMaster node must be considered a 'special' node (single point of failure),
meaning that the node must be protected more than the other commodity machines. It should
be possible to instead have the HMaster be much more available, either in a distributed sense
(meaning a bit rewrite) or with multiple instances and automatic failover.
