URL: https://issues.apache.org/jira/browse/HDFS-16821 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs > Reporter: Simbarashe Dzinamarira > Assignee: Simbarashe Dzinamarira > Priority: Major > Labels: pull-request-available > > Serving reads consistently from Observer Namenodes is a feature that was > introduced in HDFS-12943. > Clients opt-into this feature by configuring the ObserverReadProxyProvider. > It is important that the opt-in is explicit because for third-party reads to > remain consistent, these clients then need to perform an msync before reads. > In HDFS-13522, the ClientGSIContext is implicitly added to the DFSClient thus > enabling Observer reads for all clients by default. This breaks consistency > guarantees for clients that haven't opted into observer reads. > [https://github.com/apache/hadoop/pull/4883/files#diff-a627e2c1f3e68235520d3c28092f4ae8a41aa4557cc530e4e6862c318be7e898R352-R354] > We need to return to the old behavior of only using the ClientGSIContext when > users have explicitly opted into Observer reads. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
