Hello Andrew Wong, Adar Dembo, Todd Lipcon, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/12445 to look at the new patch set (#4). Change subject: [security] KUDU-2695 fix CheckOpenSSLInitialized() ...................................................................... [security] KUDU-2695 fix CheckOpenSSLInitialized() With OpenSSL 1.1.0, the CRYPTO_get_locking_callback() and the whole old threading API has been removed. With the new threading API in OpenSSL, there is no need to set locking callbacks. In other words, starting with OpenSSL 1.1.0, the library is initialized to be multithread-safe, and that's exactly what Kudu needs from the OpenSSL's initialization. Prior to this patch, the sample C++ Kudu client application from $KUDU_ROOT/examples/cpp with added call of KUDU_CHECK_OK(kudu::client::DisableOpenSSLInitialization()); would fail on Ubuntu 18.04 with error message like below: Bad status: Runtime error: Locking callback not initialized Prior to this patch, the sample Python Kudu client application from $KUDU_HOME/examples/python/basic-python-example/basic_example.py was failing exactly as reported in KUDU-2695. With this patch, the same modified C++ Kudu client application works fine at Ubuntu 18.04 (OpenSSL 1.1.0g, with packages libssl-dev:amd64@1.1.0g-2ubuntu4.3, libssl1.1:amd64@1.1.0g-2ubuntu4.3). The above mentioned Python example also works as intended with this fix. I also verified that the kudu CLI utility works fine and uses TLS wire encryption with this patch.
