      Description

      Today when Zookeeper quorum is incorrect, then both CDAP Master and Upgrade Tool on startup hang while connecting to the non-existent Zookeeper. The processes hang for hours without timing out, and without any indication of what is going on. This leads to a really bad user experience, where user does not know what is happening.

      We need to figure out how to fail fast in such cases.
