Subject [jira] [Commented] (HIVE-9500) Support nested structs over 24 levels.
Date Wed, 28 Jan 2015 18:18:36 GMT


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?

> 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).
