Erik Krogen reassigned HDFS-13779: ---------------------------------- Assignee: Erik Krogen > Implement performFailover logic for ObserverReadProxyProvider. > -------------------------------------------------------------- > > Key: HDFS-13779 > URL: https://issues.apache.org/jira/browse/HDFS-13779 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs-client > Reporter: Konstantin Shvachko > Assignee: Erik Krogen > Priority: Major > > Currently {{ObserverReadProxyProvider}} inherits {{performFailover()}} method > from {{ConfiguredFailoverProxyProvider}}, which simply increments the index > and switches over to another NameNode. The logic for ORPP should be smart > enough to choose another observer, otherwise it can switch to a SBN, where > reads are disallowed, or to an ANN, which defeats the purpose of reads from > standby. > This was discussed in HDFS-12976. -- 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
