> Block replication fails continuously when the replication target node is dead
> -----------------------------------------------------------------------------
>
> Key: SPARK-3495
> URL: https://issues.apache.org/jira/browse/SPARK-3495
> Project: Spark
> Issue Type: Bug
> Components: Block Manager, Spark Core, Streaming
> Affects Versions: 1.0.2, 1.1.0
> Reporter: Tathagata Das
> Assignee: Tathagata Das
> Priority: Critical
> Fix For: 1.2.0
>
>
> If a block manager (say, A) wants to replicate a block and the node chosen
> for replication (say, B) is dead, then the attempt to send the block to B
> fails. However, this continues to fail indefinitely. Even if the driver
> learns about the demise of the B, A continues to try replicating to B and
> failing miserably.
> The reason behind this bug is that A initially fetches a list of peers from
> the driver (when B was active), but never updates it after B is dead. This
> affects Spark Streaming as its receiver uses block replication.
