Seems we need both key and value from the prevCell in FastDiffDeltaEncoder and all. Just add a comment saying so. Normally we copy the key part alone in beforeShipped

Why not making it ShipperListener. That would be best

If do so, we should move ShipperListener to hbase-common first

So many method exposes for the test-ability. Are we really testing the FT way? That a prevCell been passed and we pollute that cell's backing BB/byte[] after a shipped call? That would be the best and in that I dont think we need to expose these many method.

The UT is not really doing a meaningful test. Write a cell first and then pollute its backing ByteBuffer by directly manipulating few bytes which comes at some KeyLen part or so. Then write another cell. Call the beforeShipped() before manipulating this 1st BB. With out the patch, we will end up in some issues. The patch should fix it.
Even we can remove all these new getters exposed in different classes for testing.
