Íñigo Goiri commented on HDFS-12422:
------------------------------------
Thanks [~lukmajercak] for the ping.
The whole fix is to remove the if that skips the recovery:
{code}
} else if (stage == BlockConstructionStage.PIPELINE_CLOSE
|| stage == BlockConstructionStage.PIPELINE_CLOSE_RECOVERY) {
//pipeline is closing
return;
}
{code}
> Replace DataNode in Pipeline when waiting for Last Packet fails

> # Create a file with replicationFactor = 4, minReplicas = 2
> # Fail waiting for the last packet, followed by 2 exceptions when recovering
> the leftover pipeline
> # The leftover pipeline will only have one DN and NN will never close such
> block, resulting in failure to write
> The block will stay there forever, unable to be replicated, ultimately going
> missing.
