Hi ,
I think there is a bug in HBaseAdmin.getConnection(). The reason is In HConnectionManager the connection object is cached based on the HConnectionKey. The equals method checks the value of the CONNECTION_PROPERTIES. Suppose if we do a restart/switch of the master and again try to do an enable table operation then in the test code we will create a new HBaseAdmin object. But the connection that the Admin creates to the Master is taken from the cache though it is a new connection. Here none of the values in the CONNECTION_PROPERTIES is changed so we get the same connection object, the one when the previous master was active and hence though the master has been restarted we get the old active master address and hence an exception is thrown. So in order to pass the test case we change the value of one of the CONNECTION PROPERTIES so that the cached connection object is not returned. Correct me if am wrong? Am getting this problem when i try to run the test case of HBASE-4052 in trunk. This is one of the problems that I faced. Other one is that the region server doesnt checkin after master switch has happened. I overcame this by changing the value for one of the CONNECTION PROPERTIES.(a workaround).
