Ted Yu commented on HBASE-7369:
-------------------------------

The above test failures seem to tell us something.
e.g. I got the following based on patch v4:
{code}

> When an HConnection is abort()'ed (i.e. if numerous services are lost) the connection
becomes unusable. HConnectionManager cache of HConnections currently does not have any logic
around removing aborted connections automatically. Currently it is up to the consumer to do
so using HConnectionManager.deleteStaleConnection(HConnection).
