Probably someone can provide details as to your other questions, this is what I think i can help with:

>Does Hadoop pageview data go back that far?

Hadoop data is only for the last 30 days.

>Back when MediaViewer was launched, I added a namespace parameter to NavigationTiming to be able to track per-namespace pageviews,

Navigation timing is heavily sampled so I am not sure you could estimate pageviews with the scarce dataset it provides, I would say it is not possible.

I would like to graph the correlation between file namespace page views and MediaViewer image views. Back when MediaViewer was launched, I added a namespace parameter to NavigationTiming to be able to track per-namespace pageviews, but I messed up and it only got deployed around the time MediaViewer was enabled on Commons, so we have no data for the early steps of the deploy process.

Do you know of any other source for per-namespace pageview data that is still available for the 2014 April-June period? Technically the raw pagecount files contain the information but aggregating those would be a horribly complicated way of getting this information. Does Hadoop pageview data go back that far?

thanks
