Dongjoon Hyun commented on SPARK-18105:
---------------------------------------

I agree with [~viirya] that this might be not a LZ4 codec issue.

To [~arghya18], more info would be definitely helpful of course.
> I can provide any further info required for debugging. 

Yep. That's the reason why this issue is still open. If we have a deterministic 
reproducible example, it will be fixed already.
> The only issue of the error is its not reproducible. So out of 1000 of spark 
> job only few fails and those few are different in different days. 

FYI, LZ4-java become 1.7.1 at Apache Spark 3.0.0. So, your report on 3.1.1 is 
invaluable and [~devaraj]'s 3.0.1 report is too. For Apache Spark 3.3, we will 
use LZ4-java 1.8. (SPARK-36256)
