> URL: https://issues.apache.org/jira/browse/HDFS-17111
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Simbarashe Dzinamarira
> Assignee: Simbarashe Dzinamarira
> Priority: Major
> Labels: pull-request-available
>
> Right now when a client MSYNCs to the router, the call is fanned out to all
> nameservices. We only need to proxy the msync to nameservices that have
> observer reads configured.
> We can do this either by adding a new config for the admin to specify which
> nameservices have CRS configured, or we can try to automatically detect these.
