Colin Patrick McCabe updated HDFS-5644:
---------------------------------------
Description: libhdfs has a hash table which contains class references.
This hash table is shared between threads and currently uses a single global
lock. The scope of this issue is to improve performance of libhdfs by removing
this single global lock. (was: libhdfs uses locking internally for
coordinating access to shared hash tables and the JNI environment. The scope
of this issue is to improve performance of libhdfs by reducing lock contention.)
