Review comment:
Verify the failed tests with the following changes?
```scala
import java.lang.{Boolean => JBoolean}
val hiveClass = Utils.classForName("org.apache.hadoop.hive.ql.metadata.Hive")
val getInternalMethod = hiveClass.getDeclaredMethod("getInternal",
classOf[HiveConf], classOf[Boolean], classOf[Boolean], classOf[Boolean])
getInternalMethod.setAccessible(true)
val c = getInternalMethod.invoke(hiveClass, conf, JBoolean.FALSE,
JBoolean.FALSE, JBoolean.FALSE).asInstanceOf[Hive]
clientLoader.cachedHive = c
```
