Description

In the hdfsThreadDestructor() function, we ignore the return value from the DetachCurrentThread() call. We are seeing cases where a native thread dies while holding a JVM monitor, and it doesn't release the monitor. We're hoping that logging this error instead of ignoring it will shed some light on the issue. In any case, it's good programming practice.
