Use JNA to allocate buffers in the block cache
----------------------------------------------
Key: HBASE-4026
URL: https://issues.apache.org/jira/browse/HBASE-4026
Project: HBase
Issue Type: Improvement
Components: regionserver
Reporter: Jason Rutherglen
Priority: Minor
The HBase block cache can be problematic because it is unpredictable when Java
will reclaim the unused byte arrays using garbage collection.
JNA (Java Native Access from Sun/Oracle) provides one possible way to solve
this problem.

Memory is the name of the class that can be used to test the implementation.
