> EditLogTailer#doTailEdits currently catches, logs, and swallows EditLogInputException.
This is fine in the case when the standby is sitting idly behind tailing logs. However, when
the standby is transitioning to active, swallowing this exception is incorrect, since it could
cause the standby to silently fail to load all the edits before becoming active.
