The major from-scratch job in the pre-merge tests seems to frequently be taking more than 5 hours. It used to frequently take less than 4, as of a month or two ago.
Here's a job that calls that, to show how long the job has been taking recently: https://jenkins.impala.io/view/Utility/job/parallel-all-tests/buildTimeTrend Was something big added that increased the run time? It's possible I missed an email thread about this.
