Jimmy Xiang commented on HBASE-5353:
------------------------------------
Another option is not to have a master, every region server can do the work a
master currently does. Just uses the ZK to coordinate them.
For example, once a region server dies, all other region server knows about it,
all try to run the dead server clean up, but only one will actually do it. The
drawback here is too much zk interaction.
> HA/Distributed HMaster via RegionServers

> Key: HBASE-5353
> URL: https://issues.apache.org/jira/browse/HBASE-5353
> Project: HBase
> Issue Type: Improvement
> Components: master, regionserver
> Affects Versions: 0.94.0
> Reporter: Jesse Yates
> Priority: Minor
>
> 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.
