Aaron T. Myers commented on HDFS-1973: -------------------------------------- bq. A general note: this failover proxy provider doesn't get passed enough info to choose different configs based on the "logical URI". For example, if I have two clusters, foo and bar I'd expect to be able to configure dfs.ha.namenodes.foo separately from dfs.ha.namenodes.bar after setting both of dfs.client.failover.proxy.provider.foo|bar. I've filed HDFS-2367 to address this issue. > HA: HDFS clients must handle namenode failover and switch over to the new > active namenode. > ------------------------------------------------------------------------------------------ > > Key: HDFS-1973 > URL: https://issues.apache.org/jira/browse/HDFS-1973 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Suresh Srinivas > Assignee: Aaron T.
