Chen Liang created HDFS-14016: --------------------------------- Summary: ObserverReadProxyProvider can never enable observer read except in tests Key: HDFS-14016 URL: https://issues.apache.org/jira/browse/HDFS-14016 Project: Hadoop HDFS Issue Type: Sub-task Reporter: Chen Liang Assignee: Chen Liang
Currently in {{ObserverReadProxyProvider#invoke}}, only when {{observerReadEnabled && isRead(method)}} is true, the code will check whether to talk to Observer. Otherwise always talk to active. The issue here is that currently it can only be set through {{setObserverReadEnabled}}, which is used by tests only. So observer read is always disabled in deployment and no way to enable it. We may want to either expose a configuration key, or hard code it to true so it can only be changed for testing purpose, or simply remove this variable. This is closely related to HDFS-13923. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
