Duo Zhang commented on HBASE-19793:
-----------------------------------
There are bunch of initialization code for a fresh cluster, not only cluster
id. So it is not a good idea to move them into the constructor.
But anyway, let me add some comments and do some refactoring to make the start
up code more readable.
> Move the cluster id initialization to the very beginning

> Both ZooKeeper and hadoop FileSystem can do fencing, that means, if two
> processes try to create one file, only one of them can succeed. So I think we
> can move the initialization of ClusterId to the very beginning instead of
> only allow active master to do it.
> This may helps us solve the complicated dependency issue.
