Because of the avro serialization issue we cannot backfill hadoop. The data has been lost. Will remove those rows for now but will try imputing and make a note.

@mpopov This doesn't seem to be done, as there's no note on the dashboards about why the data is missing. I'm moving this back to the backlog.

Deskana triaged this task as Normal priority.
