Konstantin Shvachko closed HDFS-2064. ------------------------------------- > 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: namenode > Affects Versions: 0.22.0 > Reporter: Konstantin Shvachko > Assignee: Konstantin Shvachko > Attachments: WarmHA-GoingHot.pdf, failover-v-0.22.patch, > failover-v-0.22.patch, failover-v-0.22.patch > > > 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 was sent by Atlassian JIRA (v6.2#6252)
