Gregory Chanan commented on HBASE-7170:
---------------------------------------
I traced its history, it was in the initial commit of HConnectionManager:
https://github.com/apache/hbase/commit/07657c40e9528b32bb17f2af72f3b3c34eeada7f
so no additional information on why it was there in the first place.

> HBASE-5058 retained the old behavior of managed HConnections not retrying
> their connection to master b/c of the "masterChecked" variable.
> This behavior isn't great though, because you can get in the following
> situation:
> 1) Connect to master using HBaseAdmin
> 2) Master goes down
> 3) New master takes over
> 4) The HBaseAdmin object is now useless
> The client needs to create a new HBaseAdmin in this case.
