> Optionally shut down datanode if it does not stay connected to active namenode
> ------------------------------------------------------------------------------
>
> Key: HDFS-16918
> URL: https://issues.apache.org/jira/browse/HDFS-16918
> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
>
> While deploying Hdfs on Envoy proxy setup, depending on the socket timeout
> configured at envoy, the network connection issues or packet loss could be
> observed. All of envoys basically form a transparent communication mesh in
> which each app can send and receive packets to and from localhost and is
> unaware of the network topology.
> The primary purpose of Envoy is to make the network transparent to
> applications, in order to identify network issues reliably. However,
> sometimes such proxy based setup could result into socket connection issues
> b/ datanode and namenode.
> Many deployment frameworks provide auto-start functionality when any of the
> hadoop daemons are stopped. If a given datanode does not stay connected to
> active namenode in the cluster i.e. does not receive heartbeat response in
> time from active namenode (even though active namenode is not terminated), it
> would not be much useful. We should be able to provide configurable behavior
> such that if a given datanode cannot receive heartbeat response from active
> namenode in configurable time duration, it should terminate itself to avoid
> impacting the availability SLA. This is specifically helpful when the
> underlying deployment or observability framework (e.g. K8S) can start up the
> datanode automatically upon it's shutdown (unless it is being restarted as
> part of rolling upgrade) and help the newly brought up datanode (in case of
> k8s, a new pod with dynamically changing nodes) establish new socket
> connection to active and standby namenodes. This should be an opt-in behavior
> and not default one.
