      Description

      In an HA setup I was running for the past week, I just noticed that checkpoints weren't getting properly uploaded, since the SBN was connecting to http://0.0.0.0:50070/ rather than the correct dfs.http.address. So, it was uploading checkpoints to itself instead of the peer. We should add sanity checks during startup to ensure that the configuration is correct.
