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

             Summary: OpensslCipher initialization error should log a WARN message
                 Key: HADOOP-17982
                 URL: https://issues.apache.org/jira/browse/HADOOP-17982
             Project: Hadoop Common
          Issue Type: Improvement
          Components: kms, security
            Reporter: Wei-Chiu Chuang


We spent months troubleshooting a RangerKMS performance problem, only to realize that the openssl library wasn't even loaded properly.

The failure to load openssl lib is currently logged as a debug message during initialization. We really should upgrade it to at least INFO/WARN. 

{code}
static {
    String loadingFailure = null;
    try {
      if (!NativeCodeLoader.buildSupportsOpenssl()) {
        PerformanceAdvisory.LOG.debug("Build does not support openssl");
        loadingFailure = "build does not support openssl.";
      } else {
        initIDs();
      }
    } catch (Throwable t) {
      loadingFailure = t.getMessage();
      LOG.debug("Failed to load OpenSSL Cipher.", t);
    } finally {
      loadingFailureReason = loadingFailure;
    }
  }
{code}
