Daniel Dai commented on HIVE-17115:
-----------------------------------
[~erik.fang], I find if SerDe.initialize throw exception, the create table
statement would also fail as it will go through the same
MetaStoreUtils.getDeserializer code. Do you know how this table is created and
why we don't see exception at time of creation?
> MetaStoreUtils.getDeserializer doesn't catch the
> java.lang.ClassNotFoundException
