bug: org.apache.comet.CometNativeException: range end index 8221 out of range for slice of length 8192 #498
Description
Describe the bug
It looks like we may have a hard-coded assumption in shuffle where we cannot process an incoming batch that is larger than the default batch size.
I have seen this error more than once but currently have a repro so will document this more as I investigate.

I don't see this before. If there is reproducible example for this, it will be easier to debug.

Ah, I probably found where it goes wrong.
