@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.
