> RBF: Refresh cacheNS when SocketException occurs
> ------------------------------------------------
>
> Key: HDFS-15555
> URL: https://issues.apache.org/jira/browse/HDFS-15555
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: rbf
> Environment: HDFS 3.3.0, Java 11
> Reporter: Akira Ajisaka
> Assignee: Akira Ajisaka

> Problem:
> When active NameNode is restarted and loading fsimage, DFSRouters
> significantly slow down.
> Investigation:
> When active NameNode is restarted and loading fsimage, RouterRpcClient
> receives SocketException. Since
> RouterRpcClient#isUnavailableException(IOException) returns false when the
> argument is SocketException, the MembershipNameNodeResolver#cacheNS is not
> refreshed. That's why the order of the NameNodes returned by
> MemberShipNameNodeResolver#getNamenodesForNameserviceId(String) is unchanged
> and the active NameNode is still returned first. Therefore RouterRpcClient
> still tries to connect to the NameNode that is loading fsimage.
> After loading the fsimage, the NameNode throws StandbyException. The
> exception is one of the 'Unavailable Exception' and the cacheNS is refreshed.
> Workaround:
> Stop NameNode and wait 1 minute before starting NameNode instead of
> restarting.
