(was: Suresh,
Wanted to give you some background and context here
As you may know we are working with Pivotal and they are going to white
label HDP as PHD starting with PHD 3.0.
They have raised the issue of 3 patches that were in their Hadoop distro
that are critical for HAWQ to work. We have asked them to create Apache
JIRAs so our experts can evaluate them and consider for inclusion in HDP.
Hopefully they will add some more detail soon

> Datanode should not trust the generation stamp provided by client, since it is prefetched and buffered in client, and concurrent append may increase it.
