Viraj Jasani commented on HADOOP-15984:
---------------------------------------

It turns out we can live without grizzly-http-* modules. Created sub-task 
HADOOP-18620 with [PR|https://github.com/apache/hadoop/pull/5356].

 

Though this makes upgrade path to Jersey 2 little more simplified, it is still 
very long road. We still use bunch of Jersey 1.x APIs in Yarn that literally no 
longer exists in Jersey 2.x (without any replacement). I have tried to look 
into their old commits that removed these classes, could not find any 
explanation as to why any form of backward compatibility or compatible APIs 
were not provided in Jersey 2.

 

But for now, getting rid of all grizzly-http-* modules is definitely good idea, 
given how messy it has been managed so far.

Thanks again [~jackxu2011] for the suggestion!
