Hi, everyone
I have some questions about creating a datasource table.
In HiveExternalCatalog.createDataSourceTable,
newSparkSQLSpecificMetastoreTable will replace the table schema with
EMPTY_DATA_SCHEMA and table.partitionSchema.
So,Why we use EMPTY_DATA_SCHEMA? Why not declare schema in other way?
There are a lot of datasource tables that don't have partitionSchema, so
they will be replaced as EMPTY_DATA_SCHEMA?
Even if Spark itself can parse, what if the user views the table
information from the Hive side?
Any one can help me?
thanks.
