@HyukjinKwon , interesting reading but I couldn't find a concrete reason or 
solution to the issue.
@cloud-fan, I've encountered this bug when working with a disk persisted 
RDD, it turned out some of our partitions exceeded the 2GB limit and failed on 
`DiskStore.getBytes`.

since we're using a specific commercial distro I couldn't test this patch 
on my use case (we got rid of the large partitions anyway by tuning number of 
partitions and tweaking the DAG altogether :sunglasses: ), so I did the next 
best thing: reproduce the issue in a test case, please see test "blocks larger 
than 2gb" in `DiskStoreSuite` inthis PR.

Sounds good to me except `BlockManagerSuite.scala`. I am not familiar 
whether this new test checks new code well or not.

Looks reasonable, can you explain which end-to-end cases this patch fixed? 
and also which end-to-end cases remain problematic.

@kiszk , fixed styling+readability according to your comments.
BTW, any idea why JIRA didn't associate this PR with SPARK-3151?
