stack commented on HBASE-5027:
------------------------------
bq. It it possible to count the number of connection open? Then we would just
have to check that it does not increase after two calls.
If you added this:
{code}
diff --git
a/src/test/java/org/apache/hadoop/hbase/client/HConnectionTestingUtility.java
b/src/test/java/org/apache/hadoop/hbase/client/HConnectionTestingUtility.java
index 17da42d..00f4541 100644

b/src/test/java/org/apache/hadoop/hbase/client/HConnectionTestingUtility.java
@@ -85,4 +85,13 @@ public class HConnectionTestingUtility {
return connection;
}
}
-}

+ /**

+ public static int getConnectionCount() {
+ synchronized (HConnectionManager.HBASE_INSTANCES) {

+ }
+ }
+}
{code}
... you could count connections. We shouldn't open access to
HCM.HBASE_INSTANCES Map. Above does it in a way that allows tests count
instances.

> Configuration reading *.xmls and then does a merge.
