Hi,

I think it is OK to deprecate the Hive 1.1 support. As of 0.4.6-SNAPSHOT that I 
was using the latest build about 3 weeks ago, I did face issues if I did want 
to work with Hive 1.1 that is bundled as a part of CDH 5.13 docker image. I did 
have to make manual tweaks listed at: 
https://github.com/bvaradar/hudi/commit/e189734a07b8782ea1d21b3c780dfc61c2ab8f2b
 
(https://link.getmailspring.com/link/[email protected]/0?redirect=https%3A%2F%2Fgithub.com%2Fbvaradar%2Fhudi%2Fcommit%2Fe189734a07b8782ea1d21b3c780dfc61c2ab8f2b&recipient=ZGV2QGh1ZGkuYXBhY2hlLm9yZw%3D%3D)
 to get it to work.
I thought at Uber CDH is being used. Have you upgraded to CDH6.x?
In summary: My experience has been that without the changes listed above hive 
1.1 has issues. So 0.4.6-SNAPSHOT didnt work for me? I think it will be great 
to document that Hive 1.1 support is deprecated and doesnt work beyond 0.4.5?
Thanks
Kabeer.
