Aihua Xu commented on HIVE-9500:
--------------------------------
[~thejas] I saw you made the change to support up to 24 levels of the nested
structs. I'm wondering why we didn't support any number of levels (even beyond
24) by a configurable setting when you were working on HIVE-3253. Any technical
barrier for that?
> Support nested structs over 24 levels.

> Currently we support up to 24 levels of nested structs when
> hive.serialization.extend.nesting.levels is set to true, while the customers
> have the requirement to support more than that.
> It would be better to make the supported levels configurable or completely
> removed (i.e., we can support any number of levels).
