what would prevent a hub from taking grease. The grease zerk is clear, but I have never been able to get one of my four trailer hubs to take grease. The other three hubs will take 2-3 pumps of grease, but not this one. Could the piston be malfunctioning and blocking the application of grease?

The piston could certainly be bad, or perhaps even the zerk fitting. Try removing the bearing buddy and applying grease while it is off of the hub.
I had the same thing happen on my jet ski trailer, I replaced the bearing buddy which fixed the problem.
