Jonathan Eagles commented on TEZ-3915:
--------------------------------------
[~harishjp], I am going to try to put up some comments on this early next week.
A 100k+ patch needs some time to review. I am in the middle of making
improvements to the Protobuf based recovery code and have found many
performance improvements that this patch could have taken advantage of
possibly. For reference see TEZ-3914. Being able to reuse the
CodedInputStream/CodedOutputStream is a big win.
