InvalidOperationException: new table <dbname>.<table> already exists

Hi,

We have a problem with drop,rename statements when using dbt-impala.

The firs dbt run command works nicely and the tables created. However, the second execution of dbt run command result like this:

$ dbt run

It says testdb.stg_orders and testdb.stg_orders tables are still there and not dropped. But when we query from Impala(HUE):
We get this error:

AnalysisException: Could not resolve table reference: 'testdb.stg_customers'

And if we query from Hive(HUE) we see the tables not dropped. To solve this problem we have to execute invalidate metadata query and Impala start to see the tables. But still tables are not dropped so rename operation failed.

    drop table if exists testdb.stg_orders

Is this error related with dbt-impala?

Thanks for helping.

Hey @bhctsntrk - can you let us know which version of the adapter you are using?

If you are on dbt-impala==1.0.4 can you give it a try dbt-impala==1.0.5rc2 - we included a fix for #16

It looks like you're using the jaffle-shop demo, where the staging models are materialised as views - I think you are likely running into #16 which is incorrectly handling those views as tables

[bhctsntrk]

Hello @sdairs , We updated to 1.0.5rc2 after encountering with #16 . For additional information our model structure is:

├── models
│   ├── customers_dbt.sql
│   └── staging
│       ├── stg_customers.sql
│       └── stg_orders.sql

'''customers_dbt.sql'''

with customers as (
    select * from {{ ref('stg_customers') }}
),

orders as (
    select * from {{ ref('stg_orders') }}
),

customer_orders as (

    select
        customer_id,

        min(order_date) as first_order_date,
        max(order_date) as most_recent_order_date,
        count(order_id) as number_of_orders

    from orders

    group by 1

),


final as (

    select
        customers.customer_id,
        customers.first_name,
        customers.last_name,
        customer_orders.first_order_date,
        customer_orders.most_recent_order_date,
        coalesce(customer_orders.number_of_orders, 0) as number_of_orders

    from customers

    left join customer_orders using (customer_id)

)

Thanks @bhctsntrk - will see if we can reproduce the error here

[sdairs]

Hi @bhctsntrk - we merged #27 included in release 1.0.5 - can you give it a try and let us know if it helps with your issue at all? Thanks

[sdairs]

@tovganesh I caught up with @bhctsntrk and it seems he is still facing the issue - we'll have to take another look at repro

[niteshy]

@bhctsntrk let me know if you are still facing this issue, I am not able to reproduce the issue in the latest version 1.3.2.
