@RStallman-legalteam Kai has signed an NDA with WMF Legal back in September 2017 (see T168046#3591921). Can i assume that is still valid?

Hi, @kai.nissen i'll handle this, i'm on clinic duty this week.

+@Nuria @elukey for analytics data requests

Does "view EventLogging data for analyzing WMDE's fundraising banner campaigns" require shell access today as it did in 2017?

Does "view EventLogging data for analyzing WMDE's fundraising banner campaigns" require shell access today as it did in 2017?

I'd assume so!

Since we've we no longer use MySQL for EventLogging, they'll need Hive access. 'analytics-privatedata-users' should be the right group.

Thanks for the clarification @Ottomata , alright!

Adjusted requested groups. So:

NOT researchers, analytics

but instead ONLY analytics-privatedata.

@kai.nissen See above, you'll need to use Hive nowadays instead of MySQL.


(and ACK, it says "either the analytics-privatedata-users or the analytics-users user group" on that page)

Yes, the NDA on file will suffice. Thanks!

@kai.nissen Have you ever used hadoop/hive before? The data is no longer in a MySQL data store.

Change 562940 had a related patch set uploaded (by Dzahn; owner: Dzahn):
[operations/puppet@production] admins: add Kai Nissen to analytics-privatedata-users

@Dzahn Alright, thanks!
@Nuria No, I've never used it before, but I'll make myself familiar with it. There are also quite some people who can help me out at WMDE.

@kai.nissen Please read data access gudelines, and familirize yourself with hadoop, it is quite different from hive, @Addshore in WMDE can help.

Access approved.

@kai.nissen Your access is now enabled (but it can take up to 30 minutes until it has propagated to all servers), let me know (reopen this task or ping me on IRC (moritzm)) if you run into any issues logging in. If you have any questions wrt Hadoop access, best to ask the #wikimedia-analytics channel on IRC.

@kai.nissen You should have also received a mail for your Kerberos account (required to access Hadoop) with further instructions.
