> Add LastHeartbeatResponseTime for BP service actor
> --------------------------------------------------
>
> Key: HDFS-16907
> URL: https://issues.apache.org/jira/browse/HDFS-16907
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
> Attachments: Screenshot 2023-02-03 at 6.12.24 PM.png

>
> BP service actor LastHeartbeat is not sufficient to track realtime connection
> breaks.
> Each BP service actor thread maintains _lastHeartbeatTime_ with the namenode
> that it is connected to. However, this is updated even if the connection to
> the namenode is broken.
> Suppose, the actor thread keeps heartbeating to namenode and suddenly the
> socket connection is broken. When this happens, until specific time duration,
> the actor thread consistently keeps updating _lastHeartbeatTime_ before even
> initiating heartbeat connection with namenode. If connection cannot be
> established even after RPC retries are exhausted, then IOException is thrown.
> This means that heartbeat response has not been received from the namenode.
> In the loop, the actor thread keeps trying connecting for heartbeat and the
> last heartbeat stays close to 1/2s even though in reality there is no
> response being received from namenode.
>
> Sample Exception from the BP service actor thread, during which LastHeartbeat
> stays very low:
> {code:java}
> 2023-02-03 22:34:55,725 WARN [xyz:9000] datanode.DataNode - IOException in
> offerService

> Attaching screenshots of how last heartbeat value looks when the above error
> is consistently getting logged.
>
> Last heartbeat response time is important to initiate any auto-recovery from
> datanode. Hence, we should introduce LastHeartbeatResponseTime that only gets
> updated if the BP service actor thread was successfully able to retrieve
> response from namenode.
