text: In our scalability tests it sometimes happens that all tests are passing, but the run is marked red as "failure". This is because uploading logs to GCS sometimes failed with error: I've seen 2 examples during last 24 hours: For now it's just misleading. However, since scalability suite is now pretty stable, I would like to add it to list of projects that our merge bot requires to be green to merge anything. Unfortunately this looks like a blocker for it. Any thoughts how to fix that? cc

Another example of it:
Yes, I think this is a good idea. It should be relatively trivial to mask the uploading error from Jenkins (in the script). We do ideally need some sort of warning to alert us if/when the uploads are failing repeatedly (which could be done in a separate PR). Ideally it would email the oncall, or automatically (re-)open and assign a github ticket. do you have time to look at this next week? Anyone else? If not, I will. Tentatively assigning to myself, although hoping that someone else will pick it up.
We're using a Jenkins plugin, not the e2e scripts, to upload build results to GCS. There's no way that I can find to make it not fail the build if an upload fails. Side note: the actual error message is a 401 error from GCS which seems to suggest an actual issue in the underlying infrastructure somewhere, which probably shouldn't be overlooked, but I have no idea where to start to try to figure which team to notify.
That said, it should be pretty straightforward to write a script to upload the artifacts and build log, rather than relying on the plugin.
Yes - that would be great if you could do it...
Just bumping it up - it happened again few times over the weekend and also today:
I looked at the existing plugin that we're using, and it does indeed retry (5 times!) Also searched the logs and found a lot of GCS errors: $ grep GoogleJsonResponseException: uniq -c 50 401 Unauthorized 22 500 Internal Server Error 12 503 Service Unavailable So I don't really think that there is much more that we can do here other than help GCS to track down their errors, and increase the retry count (although 5 with exponential backoff already seems rather excessive).
