Alan Gates commented on HIVE-16555:
-----------------------------------
I think there's a race condition in HiveMetaStore between when you check the
UUID and when you set it. getMetastoreDBUuid calls getGuidFromDB and if that
returns null, then it calls createDbGuidAndPersist which blindly writes a new
UUID. But these are called in separate transactions, so another server could
set the UUID in between and the code wouldn't detect it.
Also, in hive_metastore.thrift you create a new structure MetastoreDBProperty
but you don't seem to use it anywhere in the thrift interface.
> Add a new thrift API call for get_metastore_uuid
