Re: [RESULT][VOTE] Migrate to sponsored Travis account
Hi Chesnay,
Can we assign Flink Committers the permission of flink-ci/flink repo?
Several times, when I pushed some new commits, the old build jobs are still
in pending and not canceled.
Before we fix that, we can manually cancel some old jobs to save build
resource.
Best,
Jark
