> From the spark code it looks like this is due to a integer overflow when
> growing a buffer length. The offending line {{BufferHolder.java:36}} is the
> following in the version I'm running:
> {code}
> final byte[] tmp = new byte[length * 2];
> {code}
> This seems to indicate to me that this buffer will never be able to hold more
> then 2G worth of data. And likely will hold even less since any length >
> 1073741824 will cause a integer overflow and turn the new buffer size
> negative.
> I hope I'm simply missing some critical config setting but it still seems
> weird that we have a (rather low) upper limit on these buffers.
