For many developers working with multiple VM HDP Sandboxes this is not optimal, as we always have to tunnel each connection through the VM host into the docker container. That’s why we are building our own custom Sandbox. However, when building a kerberized Hadoop installation, it is a bit tricky to configure a hostname such that Kerberos principals resolve theRead more ..
