> When replicating large blocks with encryption, we try to allocate an array of size {{Int.MaxValue}} which is just a bit too big for the JVM.  This is basically the same as SPARK-25704, just another case.
> In DiskStore:
> {code}
> val chunkSize = math.min(remaining, Int.MaxValue)
> {code}
> {noformat}
