Arghya Saha commented on SPARK-18105:
-------------------------------------

[~dongjoon] Can we please address this before next release, this is one of the 
blocker for many.

For example, we have actually migrated our entire ETL running thousands of job 
everyday on 2PB data warehouse  from EMR to open source Spark on K8S and is 
running stable except this issue. I can provide any further info required for 
debugging. 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.
