Imran Rashid resolved SPARK-24936. ---------------------------------- Resolution: Won't Fix As we've already shipped 2.4, I think its unlikely we're going to fix this later. I don't think we need to worry that much about spark 3.0 talking to shuffle services < 2.2. If anybody is motivated, feel free to submit a pr here, but I think leaving this open is probably misleading about the status. > Better error message when trying a shuffle fetch over 2 GB > ---------------------------------------------------------- > > Key: SPARK-24936 > URL: https://issues.apache.org/jira/browse/SPARK-24936 > Project: Spark > Issue Type: Sub-task > Components: Spark Core > Affects Versions: 2.4.0 > Reporter: Imran Rashid > Priority: Major > > After SPARK-24297, spark will try to fetch shuffle blocks to disk if their > over 2GB. However, this will fail with an external shuffle service running < > spark 2.2, with an unhelpful error message like: > {noformat} > 18/07/26 07:15:02 WARN scheduler.TaskSetManager: Lost task 1.0 in stage 1.3 > (TID 15, xyz.com, executor 2): FetchFailed(BlockManagerId(1 > , xyz.com, 7337, None), shuffleId=0, mapId=1, reduceId=1, message= > org.apache.spark.shuffle.FetchFailedException: > java.lang.UnsupportedOperationException > at > org.apache.spark.network.server.StreamManager.openStream(StreamManager.java:60) > at > org.apache.spark.network.server.TransportRequestHandler.processStreamRequest(TransportRequestHandler.java:136) > ... > {noformat} > We can't do anything to make the shuffle succeed, in this situation, but we > should fail with a better error message. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
