Hi, >From now on the PreCommit-HBASE-Build job on builds.apache.org uses the flaky list for the target branch. You can still set the EXCLUDE_TESTS_URL parameter to specify different exclude list (e.g. rely on master exclude list for a branch-2.0 patch) but for that you need to manually trigger a job.
If you find any issues with the PreCommit run ping me on HBASE-21547 or reply to this email. Thanks, Peter
