Íñigo Goiri commented on HDFS-13312: ------------------------------------ As I'm working on running Hadoop on VMs, I see more and more the need to have a framework to discover servers. I played with DNS but this works for fixed setups but it's not very elastic (I'm limited to having always say 3 NNs). I'll open a JIRA in commons to define the framework and use it as the branch for working on this. As there are subparts in both HDFS and YARN this won't be a pure umbrella; I hope linking JIRAs and merging into the branch is fine. Anyway, I'll link the JIRA once I open it here and we can start the discussion there. > NameNode High Availability ZooKeeper based discovery rather than explicit > nn1,nn2 configs > ----------------------------------------------------------------------------------------- > > Key: HDFS-13312 > URL: https://issues.apache.org/jira/browse/HDFS-13312 > Project: Hadoop HDFS > Issue Type: Improvement > Components: ha, hdfs, namenode, nn > Affects Versions: 2.9.1 > Reporter: Hari Sekhon > Priority: Major > Attachments: HDFS-13312.000.patch, HDFS-13312.001.patch, > HDFS-13312.002.patch, HDFS-13312.003.patch > > > Improvement Request for HDFS NameNode HA to use ZooKeeper based dynamic > discovery rather than explicitly setting the NameNode addresses via nn1,n2 in > the configs. > One proprietary Hadoop vendor already uses ZK for Resource Manager HA > discovery - it makes sense that the open source core should do this for both > Yarn and HDFS. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
