                 Key: HADOOP-13684
                 URL: https://issues.apache.org/jira/browse/HADOOP-13684

            Reporter: Wei-Chiu Chuang

If for some reason libhadoop can not be found/loaded, Snappy complains Hadoop is not built with Snappy but it actually is.

{code:title=SnappyCodec.java}
public static void checkNativeCodeLoaded() {
      if (!NativeCodeLoader.isNativeCodeLoaded() ||
          !NativeCodeLoader.buildSupportsSnappy()) {
        throw new RuntimeException("native snappy library not available: " +
            "this version of libhadoop was built without " +
            "snappy support.");
      }
{code}
