Hi Hadoop,
First off, I want to thanks to Wei-Chiu for having me on the last week's Hadoop community sync to introduce our ideas of ARM support on Hadoop. And also for all the attendees for listening and providing suggestions. I want to provide some update on the status: 1. Our teammate has successfully donated an ARM machine to the ApacheInfra team, and it is setup for running: https://builds.apache.org/computer/arm-poc/ it might be a good idea to make use of it, like running some periodic jobs for some experiment, and it will also benifit us for discussions and asking for help on identified problems. 2. I've been keep try to test and debug sub-project by sub-project, and here is the current status for YARN: When running the whole test suits, some of the test suit will be skipped due to the rules of if some previous test fails, then skip this suit. So I manually run those test suits again to see if they can pass, the full test result is that: Total: 5688; Failure: 0; Error 15; Skipped 60 Among the 15 errors, 13 of them came from the ``Apache Hadoop YARN TimelineService HBase tests`` test suit. The other 2 came from ``Apache Hadoop YARN DistributedShell`` suit. 3. Some walk-arounds: 1) The only walk-arounds for build Hadoop on ARM is to pre-build grpc-java, which my teammates are working with the community to release a newer version with ARM support: github.com/grpc/grpc-java/issues/6364 2) For YARN tests, the TimelineService HBase suit need either HBase 1.4.8 or 2.0.2 which can only be built under protocbuf 2.5.0(HBase 1.4.8, HBase 2.0.2 external) and protocbuf 3.5.1(HBase 2.0.2 internal), so we have to pre-build them. And the new cause of the error is still under debugging. 3) The rest of the know issue and possible walk-arounds are reported to Hadoop Jira and are now under Wei-Chiu's tent jira report: https://issues.apache.org/jira/browse/HADOOP-16723 I have put all the test logs in the attachment and error related surefire reports in my github https://github.com/ZhengZhenyu/HadoopTestLogs/issues/1 (the attachment size is limited for sending mailling list), please have a check if you are interested. So, how should we move a little bit forward and make use of the ARM resources in ApacheInfra? Best Regards, Zhenyu
