> Client sleeps and holds 'dataQueue' when DataNodes are congested

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Affects Versions: 3.2.2, 3.3.1, 3.2.3
> Reporter: Yuanxin Zhu
> Assignee: Yuanxin Zhu
> Priority: Major
> Attachments: HDFS-16293.01-branch-3.2.2.patch, HDFS-16293.01.patch,

> Original Estimate: 24h
> Remaining Estimate: 24h
>
> When I open the ECN and use Terasort(500G data,8 DataNodes,76 vcores/DN) for
> testing, DataNodes are congested(HDFS-8008). The client enters the sleep
> state after receiving the ACK for many times, but does not release the
> 'dataQueue'. The ResponseProcessor thread needs the 'dataQueue' to execute
> 'ackQueue.getFirst()', so the ResponseProcessor will wait for the client to
> release the 'dataQueue', which is equivalent to that the ResponseProcessor
> thread also enters sleep, resulting in ACK delay.MapReduce tasks can be
> delayed by tens of minutes or even hours.
> The DataStreamer thread can first execute 'one = dataQueue. getFirst()',
> release 'dataQueue', and then judge whether to execute 'backOffIfNecessary()'
> according to 'one.isHeartbeatPacket()'
>
