In the test-with-docker context, rpc-mgr-kerberized-test was failing, ultimately due to the fact that the hostname was resolving to 127.0.0.1 and then back to 'localhost'. This commit applies a workaround of adding "127.0.0.1 $(hostnahostname)" to /etc/hosts, which allows the test to pass, and is what's done in bootstrap_system.sh. In the Docker context, /etc/hosts needs to be updated on every container start, because Docker tries to provide an /etc/hosts for you. Previously, we were doing a different customization (adding "hostname" to the existing "127.0.0.1" line), which wasn't good enough for rpc-mgr-kerberized-test. The original workaround, which is in "boostrap_system.sh" is still in place, but I've added more documentation about reproduction there. I've also filed HDFS-13797 to track the HDFS issue.
