[druid-user] Druid Can't get data after get some error message.

Have you set reportDropsAsExceptions: true? If so then this behavior is expected. Otherwise it’s not – you should see a log message about a drop but not an exception.

Also consider upgrading to imply-1.2.1, that has newer versions of Druid (0.9.0) and Tranquility (0.8.0).
