----------------------------------------------------------------------
I don't know whether Stefano's patch made some difference or not (fixing the
kryo serialization) but just removing the following code in the HashPartition
made everything work in my case (actually I don't know it the results are
correct or not but at least the process was able to complete..):
{code}
if (getNumOccupiedMemorySegments() < 2) {
throw new RuntimeException("Bug in Hybrid Hash Join: " + "Request to
spill a partition with less than two buffers.");
}
{code}
I hope this could be helpful..
