--------------------------------------

             Summary: Improve versioning and compatibility support in native library for downstream
hadoop-common users.
                 Key: HADOOP-11127
                 URL: https://issues.apache.org/jira/browse/HADOOP-11127
             Project: Hadoop Common
          Issue Type: Bug
          Components: native
            Reporter: Chris Nauroth


There is no compatibility policy enforced on the JNI function signatures implemented in the
native library.  This library typically is deployed to all nodes in a cluster, built from
a specific source code version.  However, downstream applications that want to run in that
cluster might choose to bundle a hadoop-common jar at a different version.  Since there is
no compatibility policy, this can cause link errors at runtime when the native function signatures
expected by hadoop-common.jar do not exist in libhadoop.so/hadoop.dll.
