Warm HA NameNode going Hot -------------------------- Key: HDFS-2064 URL: https://issues.apache.org/jira/browse/HDFS-2064 Project: Hadoop HDFS Issue Type: New Feature Components: name-node Affects Versions: 0.22.0 Reporter: Konstantin Shvachko Assignee: Konstantin Shvachko
This is the design for automatic hot HA for HDFS NameNode. It involves use of HA software and LoadReplicator - external to Hadoop components, which substantially simplify the architecture by separating HA- from Hadoop-specific problems. Without the external components it provides warm standby with manual failover. -- This message is automatically generated by JIRA.
