Matei Zaharia updated SPARK-2670:
---------------------------------
Assignee: Kousuke Saruta
> FetchFailedException should be thrown when local fetch has failed
> -----------------------------------------------------------------
>
> Key: SPARK-2670
> URL: https://issues.apache.org/jira/browse/SPARK-2670
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.0.0
> Reporter: Kousuke Saruta
> Assignee: Kousuke Saruta
> Priority: Critical
> Fix For: 1.1.0
>
>
> In BasicBlockFetchIterator, when remote fetch has failed, then FetchResult
> which size is -1 is set to results.
> {code}
> case None => {
> logError("Could not get block(s) from " + cmId)
> for ((blockId, size) <- req.blocks) {
> results.put(new FetchResult(blockId, -1, null))
> }
> {code}
> The size -1 means fetch fail and BlockStoreShuffleFetcher#unpackBlock throws
> FetchFailedException so that we can retry.
> But, when local fetch has failed, the failed FetchResult is not set.
> So, we cannot retry for the FetchResult.
