-----------------------------------------------
Summary: RouterObserverReadProxyProvider should respect observer
read opt-out via dfs.client.rbf.observer.enabled=false flag.
Key: HADOOP-18827
URL: https://issues.apache.org/jira/browse/HADOOP-18827
Project: Hadoop Common
Issue Type: Improvement
Environment: 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.
