----------------------------------
I have written up metastore upgrade instructions here:
http://wiki.apache.org/hadoop/Hive/ViewDev#Metastore_Upgrades
> CREATE VIEW followup: add a "table type" enum attribute in metastore's
> MTable, and also null out irrelevant attributes for MTable instances which
> describe views

> Zheng's description:
> 5. TODO: Metadata change: We store "view" definitions in the same metadata
> table that we store "table" definitions.
> Shall we add a field "table type" so we know whether it's a table, external
> table, view, or materialized view in the future.
> We should clean up the additional useless fields in "view" - the test output
> shows that we are storing some garbage information for views.
