Subject [jira] [Commented] (HBASE-5353) HA/Distributed HMaster via RegionServers
Date Thu, 09 Feb 2012 02:32:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5353?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204204#comment-13204204

Eli Collins commented on HBASE-5353:
------------------------------------

@Jesse, how is the HMaster machine a single point of failure? A SPOF is a part of the system
that, if it fails, sstop the entire system from working. Because there's automatic HMaster
failover that's not the case for HBase.

> 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.
