-------------------------------------

Thanks for addressing this.
I've look through the patch (haven't applied it) but it doesn't touch any java
code. In order to fix this this check needs to be addressed.
https://github.com/apache/hive/blob/master/metastore/src/java/org/apache/hadoop/hive/metastore/MetaStoreUtils.java#L696
Used here:
https://github.com/apache/hive/blob/master/metastore/src/java/org/apache/hadoop/hive/metastore/MetaStoreUtils.java#L708
I can confirm that changing the COLUMNS_V2.COLUMN TYPE_NAME as done in the
patch fixes the DB issue but a create/alter table will still fail due to the
error described in this ticket.

> doesn't happen , for tables with higher type length. Different users can
> change this variable based on different use cases/metastore if this can be a
> config variable.
