Hi [~James C]

pls set the fix version while committing patch.  HDFS-8707 seems the fix 
version for this. Correct?

James Clampffer commented on HDFS-12134:


w.r.t. lack of new and modified tests: Added a bunch, they just don't get 
picked up by test4tests yet, hoping to figure that out soon.  If anyone knows 
their way around the build system and wants to contribute that'd be really 
appreciated.  HDFS-12168 filed for getting it working.

{{include/hdfspp/locks.h}}: Remove additional variable {{finalize_}} and just 
use {{gssapiMtx}} for checks
Can we remove {{InitLocks}} method and initialize via {{options}}? This will 
prevent misuse of the API by invoking {{InitLocks}} multiple times.
 
Make {{bool _locked}} an {{std::atomic_bool _locked}}
use {{volatile}} to be safe for other Lock class fields.

{{lib/common/locks.cc}}: 51 should be {{_mtx.try_lock()}}

Thanks!
