Hi All,
I try to run a simple sort by on 1.2.1. And it always give me below two
errors:
1, 15/03/20 17:48:29 WARN TaskSetManager: Lost task 2.0 in stage 1.0 (TID
35, ip-10-169-217-47.ec2.internal): java.io.FileNotFoundException:
/tmp/spark-e40bb112-3a08-4f62-9eaa-cd094fcfa624/spark-58f72d53-8afc-41c2-ad6

6 (Too many open files)
And then I switch to:
conf.set("spark.shuffle.consolidateFiles", "true")
.set("spark.shuffle.manager", "SORT")
Then I get the error:
Exception in thread "main" org.apache.spark.SparkException: Job aborted due
to stage failure: Task 5 in stage 1.0 failed 4 times, most recent failure:
Lost task 5.3 in stage 1.0 (TID 36, ip-10-169-217-47.ec2.internal):
com.esotericsoftware.kryo.KryoException: java.io.IOException: File too large
at com.esotericsoftware.kryo.io.Output.flush(Output.java:157)
I roughly know the first issue is because Spark shuffle creates too many
local temp files (and I don't know the solution, because looks like my
solution also cause other issues), but I am not sure what means is the
second error.
Anyone knows the solution for both cases?
Regards,
Shuai
