Review comment:
Wouldn't this end up in a null pointer exception, when we have a
HiveException?

Review comment:
It is not related to this change, but it seems to me that the javadoc
and the naming of the method are not in sync. Maybe we should separate the
logic which is strictly related to storing serializable table data from the
code which updates table properties.

Review comment:
Are we certain that the partition column name cannot contain `,`?

Review comment:
Can we do a similar check to in production code as well? It would be
good to warn the end user about this limitation.
