Himanshu Vashishtha commented on HBASE-8294:
--------------------------------------------
Good point. I see hbase replication also has a use case like that.
In such case, we can also have an api to create a new instance.
Idea behind this jira is, currently whenever we call
HBaseConfiguration.create(), it creates a new object, which is pretty
expensive. And, there is no other way to reuse it other than passing a conf
around in all the method calls... which is quite annoying at least.
> Make HBaseConfiguration a singleton class

> HBaseConfiguration.create() calls a new Configuration object. Ideally, we
