> https://github.com/apache/spark/pull/19864#discussion_r156847927
> the current HadoopFsRelation is purely based on the underlying file size
> which is not accurate and makes the execution vulnerable to errors like OOM
> Users can enable CBO with the functionalities in
> https://github.com/apache/spark/pull/19864 to avoid this issue
> This JIRA proposes to add a configurable factor to sizeInBytes method in
> HadoopFsRelation class so that users can mitigate this problem without CBO
