Siddharth Seth commented on YARN-515:
-------------------------------------
Missed this while reviewing YARN-440... also in the second (probably biased)
review when this jira was opened. Sorry about that.
bq. I just think all this extra code to try and wrap the protocol buffers is
just a bad idea. It makes things difficult to change a .proto file
Agree with this. Seemed useful at the time, but the PBImpl stuff is rather
painful to maintain, without adding a whole lot of value.

> The Null pointer exception just keeps repeating and all of the nodes end up
> being lost. It looks like it never gets the secret key when it registers.
