I'm in the process of unifying a column name between different EventLogging schemas, to make for less confusing joins. However, when querying data before the rename, the old column name is the one that has data, on more recent rows, it's the new column. This is less than ideal.
Is there a simple way to rename the column in hive rows that were recorded prior to the column name change?
The tables that will need this are NavigationTiming (very large) and QuickSurveysResponses/QuickSurveyInitiation (small)
