> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.2
> Environment: AWS m4.10xlarge with EBS (io1 drive, 400g, 4000iops)

> 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
