Hi again,

This bug caused yet another delay in EventLogging data in Hive that I
thought I should let you know about.  A few hours on December 17th were not
refined until today.  If you have any non-Oozie jobs built on this data,
you may need to check up on them in case they need to be rerun.

More info here: https://phabricator.wikimedia.org/T213602.  Sorry for the
inconvenience.
