[jira] [Updated] (HADOOP-18827) RouterObserverReadProxyProvider should respect observer read opt-out via dfs.client.rbf.observer.enabled=false flag.
[ https://issues.apache.org/jira/browse/HADOOP-18827?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Simbarashe Dzinamarira updated HADOOP-18827:
--------------------------------------------
Environment: (was: The "dfs.client.rbf.observer.enabled" flag was add to allow a client using IPFailoverProxyProvider to use observer reads with routers.
Now we have implemented the RouterObserverReadProxyProvider which better supported observer reads, i.e performing msync automatically.
In our environment, we still have clients that opted out of observer reads by setting "dfs.client.rbf.observer.enabled=false". The RouterObserverReadProxyProvider should respect the opt-out decision of these clients.)
> RouterObserverReadProxyProvider should respect observer read opt-out via dfs.client.rbf.observer.enabled=false flag.
