Sergey Shelukhin commented on HIVE-11911:
-----------------------------------------

[~prasanth_j] see the exception text I added; you can increase prefix size by 
configuring mysql.

[~ashutoshc] maybe, but that's a separate discussion. For now we should fix it. 

> The stats table limits are too large for innodb

> The limits were increased to a reasonable value some time ago, apparently 
> these values are too large for innodb due to some index limit nonsense. We 
> need to decrease them a little bit.
> There's no need to decrease them in an upgrade script; if they were already 
> created successfully it's ok to have them as is.
