Mitesh created SPARK-20112: ------------------------------ Summary: SIGSEGV in GeneratedIterator.sort_addToSorter Key: SPARK-20112 URL: https://issues.apache.org/jira/browse/SPARK-20112 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.0.2 Environment: AWS m4.10xlarge with EBS (io1 drive, 400g, 4000iops) Reporter: Mitesh
I'm seeing a very weird crash in GeneratedIterator.sort_addToSorter. The hs_err_pid and codegen file are attached (with query plans). Its not a deterministic repro, but running a big query load, I eventually see it come up within a few minutes. Here is some interesting repro information: - Using r3.8xlarge machines, which have ephermal attached drives, I can't repro this. So I think that means its not an issue with the code-gen, but I cant figure out what the difference in behavior is. - The broadcast joins in the plan are all small tables. I have autoJoinBroadcast=-1 because I always hint which tables should be broadcast. - As you can see from the plan, all the sources are cached memory tables {noformat} # A fatal error has been detected by the Java Runtime Environment: # # [thread 139872345896704 also had an error] SIGSEGV (0xb) at pc=0x00007f38a378caa3, pid=19271, tid=139872342738688 # # JRE version: Java(TM) SE Runtime Environment (8.0_60-b27) (build 1.8.0_60-b27) # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.60-b23 mixed mode linux-amd64 compressed oops) [thread 139872348002048 also had an error]# Problematic frame: # J 28454 C1 org.apache.spark.sql.catalyst.expressions.GeneratedClass$GeneratedIterator.sort_addToSorter$(Lorg/apache/spark/sql/catalyst/expressions/GeneratedClass$GeneratedIterator;)V (369 bytes) @ 0x00007f38a378caa3 [0x00007f38a378b5e0+0x14c3] {noformat} -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
