David Mollitor commented on HIVE-21414:
---------------------------------------
[~pvary] Ya. I guess it doesn't. But it is required as part of the solution...
this patch makes it invalid to set the comments on the file itself... because
comments are stored in HMS... kinda stuck on figuring out how column comments
are handled. Are you able to point me in the right direction?
