Description

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.

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;
    }
  }
