Hitesh Shah commented on TEZ-3086:
----------------------------------
I am not sure I understand the older than 0.5.2. For amWebServiceVersion, v2 I
believe was introduced in 0.7.x. Likewise for callercontext info, etc. Which
aspect of the changes are needed for prior to 0.5.2? Additionally, the Tez UI
was not introduced until 0.6.x I believe. How does 0.5.2 come into the picture
here?
> Tez UI 2: Backward compatibility changes
