Haibo Chen commented on YARN-5667: ---------------------------------- Thanks for the update [~sjlee0]. Let's wait until they are finished. > Move HBase backend code in ATS v2 into its separate module > ----------------------------------------------------------- > > Key: YARN-5667 > URL: https://issues.apache.org/jira/browse/YARN-5667 > Project: Hadoop YARN > Issue Type: Sub-task > Components: yarn > Reporter: Haibo Chen > Assignee: Haibo Chen > Attachments: New module structure.png, part1.yarn5667.prelim.patch, > part2.yarn5667.prelim.patch, part3.yarn5667.prelim.patch, > part4.yarn5667.prelim.patch, part5.yarn5667.prelim.patch, > pt1.yarn5667.001.patch, pt2.yarn5667.001.patch, pt3.yarn5667.001.patch, > pt4.yarn5667.001.patch, pt5.yarn5667.001.patch, pt6.yarn5667.001.patch, > pt9.yarn5667.001.patch, yarn5667-001.tar.gz > > > The HBase backend code currently lives along with the core ATS v2 code in > hadoop-yarn-server-timelineservice module. Because Resource Manager depends > on hadoop-yarn-server-timelineservice, an unnecessary dependency of the RM > module on HBase modules is introduced (HBase backend is pluggable, so we do > not need to directly pull in HBase jars). > In our internal effort to try ATS v2 with HBase 2.0 which depends on Hadoop > 3, we encountered a circular dependency during our builds between HBase2.0 > and Hadoop3 artifacts. > {code} > hadoop-mapreduce-client-common, hadoop-yarn-client, > hadoop-yarn-server-resourcemanager, hadoop-yarn-server-timelineservice, > hbase-server, hbase-prefix-tree, hbase-hadoop2-compat, > hadoop-mapreduce-client-jobclient, hadoop-mapreduce-client-common] > {code} > This jira proposes we move all HBase-backend-related code from > hadoop-yarn-server-timelineservice into its own module (possible name is > yarn-server-timelineservice-storage) so that core RM modules do not depend on > HBase modules any more. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
