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

{code}
-        HConnectionManager.deleteConnection(this, stopProxy, false);
+          if(aborted){
{code}
nit: shift the if block left by two spaces (to align with the original position of 'H').
{code}
+          }
+          else {
+              HConnectionManager.deleteConnection(this, stopProxy, false);
{code}
Move 'else {' to the end of previous line.
{code}
+    for (Entry<HConnectionKey, HConnectionImplementation> entry : 
+      HConnectionManager.HBASE_INSTANCES.entrySet()) {
+      oldHBaseInstances.put(entry.getKey(), entry.getValue());
+    }
{code}
Utilize http://docs.oracle.com/javase/6/docs/api/java/util/Map.html#putAll%28java.util.Map%29
for the two copy actions.

> 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).
