This is not exactly the situation. Currently the code to have master failover is committed in trunk but it is rough e.g. it requires some manual modifications that aren't "fun" to do to start masters on other nodes. HBASE-1357 and HBASE-1445 are about fixing that. HBASE-1448 is about making the shutdown of multiple masters easier. This is due for 0.20.
