-----------------------------------
Assignee: Sandeep Katta
> Spark 3 doesnt work with older shuffle service
> ----------------------------------------------
>
> Key: SPARK-29435
> URL: https://issues.apache.org/jira/browse/SPARK-29435
> Project: Spark
> Issue Type: Bug
> Components: Shuffle
> Affects Versions: 3.0.0
> Environment: Spark 3 from Sept 26, commit
> 8beb736a00b004f97de7fcdf9ff09388d80fc548
> Spark 2.4.1 shuffle service in yarn
> Reporter: koert kuipers
> Assignee: Sandeep Katta
> Priority: Major
>
> SPARK-27665 introduced a change to the shuffle protocol. It also introduced a
> setting spark.shuffle.useOldFetchProtocol which would allow spark 3 to run
> with old shuffle service.
> However i have not gotten that to work. I have been testing with Spark 3
> master (from Sept 26) and shuffle service from Spark 2.4.1 in yarn.
> The errors i see are for example on EMR:
> {code}
> Error occurred while fetching local blocks
> java.nio.file.NoSuchFileException:
> /mnt1/yarn/usercache/hadoop/appcache/application_1570697024032_0058/blockmgr-d1d009b1-1c95-4e2a-9a71-0ff20078b9a8/38/shuffle_0_0_0.index
> {code}
> And on CDH5:
> {code}
> org.apache.spark.shuffle.FetchFailedException:
