Trivial Description
HBASE-3777 introduced the concept of a HConnectionKey to quickly identify and compare Configuration instances which lack equals/hashCode values.
We currently have use cases where being able to key Configuration objects in a similar way would be helpful. An example of this would be maintain a cache of HTablePool instances based on the HConnectionKey instead of the Configuration instance.
I propose that HConnectionKey be made publicly available instead of its current package scope. Or another possibility would be to move it from being a static inner class to being part of the API.
