Chao Sun commented on HDFS-12976: --------------------------------- [~xkrogen]: let me know if I misunderstood anything - if someone is using {{ConfiguredFailoverProxyProvider}} and received a read request, then the proxy may forward this request to a observer node, right? the observer node will then happily process this request without throwing any exception. This doesn't look like the right behavior as in future we may add some client-side flag to control whether read requests should go to observer or not. > Introduce ObserverReadProxyProvider > ----------------------------------- > > Key: HDFS-12976 > URL: https://issues.apache.org/jira/browse/HDFS-12976 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs-client > Reporter: Konstantin Shvachko > Assignee: Chao Sun > Priority: Major > Attachments: HDFS-12976-HDFS-12943.000.patch, > HDFS-12976-HDFS-12943.001.patch, HDFS-12976-HDFS-12943.002.patch, > HDFS-12976-HDFS-12943.003.patch, HDFS-12976.WIP.patch > > > {{StandbyReadProxyProvider}} should implement {{FailoverProxyProvider}} > interface and be able to submit read requests to ANN and SBN(s). -- 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
