My team maintains this dataset. We have been working on a new version which will deprecate all other pagecount and pageview datasets. Release of this new dataset is imminent. When we saw the old job failed, we couldn't fix the problem quickly and have been thinking maybe it isn't worth the effort since the new data is coming out soon.
However, if you have an immediate need, do let us know. So, in other words, if you can wait a week or two and tweak your scripts to work with the new data, that would probably be best. Otherwise, let us know and we can look at the failure more closely.
