Naveen Gangam commented on HIVE-23804:
--------------------------------------
[~aditya-shah] Can you explain a bit more on what is failing? "queries to
analyze statistics break for Hive versions <3.0.0 when used against an upgraded
DB".
So does this mean "analyze table compute statistics" is failing? what is the
failure? do you have the stack trace? I am wondering if this requires a code
fix to account for a null/empty CAT_NAME value like we do for other API calls
on the HMS side that do not have a catalog name passed in.
(MetastoreUtils.parseDBName)
I will get to your comment above later. I am trying to understand the issue
better to see what the best fix is.
