> Add period state refresh to keep router state near active namenode's
> --------------------------------------------------------------------
>
> Key: HDFS-16890
> URL: https://issues.apache.org/jira/browse/HDFS-16890
> Project: Hadoop HDFS
> Issue Type: Task
> Reporter: Simbarashe Dzinamarira
> Assignee: Simbarashe Dzinamarira
> Priority: Major
> Labels: pull-request-available
>
> When using the ObserverReadProxyProvider, clients can setÂ
> *dfs.client.failover.observer.auto-msync-period...* to periodically get the
> Active namenode's state. When using routers without the
> ObserverReadProxyProvider, this periodic update is lost.
> In a busy cluster, the Router constantly gets updated with the active
> namenode's state when
> # There is a write operation.
> # There is an operation (read/write) from a new clients.
> However, in the scenario when there are no new clients and no write
> operations, the state kept in the router can lag behind the active's. The
> router does update its state with responses from the Observer, but the
> observer may be lagging behind too.
> We should have a periodic refresh in the router to serve a similar role as
> *dfs.client.failover.observer.auto-msync-period*
