HI All, As some of you may have noticed, we have been working behind the scenes in Infra making some improvements to the overall stability and health of Jenkins.
New Nodes ========= Recently, we have added another 9 nodes H12 - H20 of which H12 to H18 are general purpose nodes for everyone. Previously we added jenkins-us1, jenkins-eu2 and jenkins-eu3 again general purpose. ubuntu-3 (Hemera) has been taken offline. New Windows Nodes - we have 2 new windows 2012 nodes, which directly replaced windows1 and windows2. Labels Removed ============= As promised some time ago, quite a few labels that were deemed no longer required, have been removed. Labels removed: yahoo-not-h2, docker, HDFS, MapReduce, Pig, Falcon, Tez and ZooKeeper. The current list of mapped Nodes to Labels can be found on our wiki page here:- https://cwiki.apache.org/confluence/display/INFRA/Jenkins+node+labels <https://cwiki.apache.org/confluence/display/INFRA/Jenkins+node+labels> In general, if you are a Hadoop related project, you would use as a priority the ‘Hadoop’ label for H0-H9 - thats 10 nodes. If not a Hadoop related project, use the ‘ubuntu’ label which currently consists of 17 nodes. You may mix n match - if appropriate use Hadoop||ubuntu for a choice of 27 nodes. For Windows, please just use the generic ‘Windows’ label - as we add more Windows nodes they will get this label. Reserved Nodes ============= There are specific nodes that have priority for projects - such as the Beam* nodes, the Cassandra* nodes etc. These are all listed in the above wiki page. These are not included in the generic ‘ubuntu’ labels. In addition, H nodes H19 and H20 are reserved - they are for all projects to use, however they are restricted to those projects that want to use Jenkins + Git + Gitpubsub in order to publish their main www website(s). I’ll do a new post up specifically on this topic soon, but we are looking for one or two projects as testers so please email if interested in knowing more. Summary ======= We have more nodes and less labels. yay! Even more nodes are coming soon also so do stay tuned. When I removed labels I also changed job configurations to replace any matching labels with alternative remaining labels. Some projects have already reverted to previous configurations and are failing to build as a result. Please check your jobs ASAP and change them in necessary, Thanks All, any questions or comments, direct to the builds@ list please. Gav… (ASF Infra.)
