Update IsolatedClientLoader.scala To resolve problem mentioned in SPARK-10529, I add an attribute of ThreadLocal<URLClassLoader> type in object IsolatedClientLoader. So, no matter how many HiveContext objects are created in the same jvm, they use the same URLClassLoader object. Therefore, no more classes will be loaded and no more jdbc connections will be created.
