The error in test_libhdfs_threaded_hdfs_static is because of an incorrect
CLASSPATH, I ran the binary by setting CLASSPATH and it passes.

> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: native
> Affects Versions: 3.0.0
> Reporter: Daniel Templeton
> Assignee: Daniel Templeton
> Priority: Major
> Attachments: HDFS-14015.001.patch, HDFS-14015.002.patch,

> 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.
