----------------------------------
Summary: 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
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.
