pyspark - can not create managed table

avatar
New Contributor

I'm writing some pyspark code where I have a dataframe that I want to write to a hive table.

I'm using a command like this.

 

dataframe.write.mode("overwrite").saveAsTable(“bh_test”)

 

Everything I've read online indicates that this should, by default, create  a managed table.

 

However, no matter what I try, it always creates an external table. Is there a configuration setting somewhere that overrides the default behavior?

Hi @haze5736, You need to use Hive Warehouse Connector (HWC) software to query Apache Hive managed tables from Apache Spark. Using HWC API you can read and write Apache Hive tables from Apache Spark. For example, to write the managed table. 

df.write.format(HiveWarehouseSession().HIVE_WAREHOUSE_CONNECTOR).option("table", &tableName>).option("partition", <partition_spec>).save()
