How to create a view with IMPALA including a query option

tsunamisabella — Tue, 21 Apr 2026 06:50:55 GMT

Hello! I am creating a view `view_business` with IMPALA: since the source table `table_a` is a parquet formatted table with complex data types such as array and struct, I have to always run an query option statement "SET PARQUET_ARRAY_RESOLUTION=TWO_LEVEL_THEN_THREE_LEVEL" to load the arrays; otherwise those array columns are showing NULL value.

DROP VIEW IF EXISTS discovery_database.view_business; SET PARQUET_ARRAY_RESOLUTION=TWO_LEVEL_THEN_THREE_LEVEL; CREATE VIEW discovery_database.view_business AS ( SELECT * FROM table_a )

Once the view is created, if I want to query the view, I still need to run the query option statement first as follows:

SET PARQUET_ARRAY_RESOLUTION=TWO_LEVEL_THEN_THREE_LEVEL; SELECT * FROM discovery_database.view_business

However, the query option statement above is not supported in ODBC connector when I tried to use the statements above to link the curated table `view_business` as a data source in a power BI report.

My question is: is it possible to create a view INCLUDING the query option statement "SET PARQUET_ARRAY_RESOLUTION=TWO_LEVEL_THEN_THREE_LEVEL", so every time when I query the view, I don't need to run this statement any more?

Thank you very much in advance!

Please note that IMPALA does not support scheduled query (to create a table instead a view). I also don't have a access right to create a scheduled query with HIVE in the HUE console. Therefore, creating a table with scheduled query cannot be the solution...

Hi, I do not think we have such option to create a view along with query option, you can follow any one of below:

> Set the query option at session level before running the query.

> Add this query option globally in impala configurations -> "default_query_options" section.

> Add it in impala admission control pool for a specific pool where this query runs, edit the pool and add the property into "Default query options" section.
