How to handle a generic internal error in Athena

问题

I have the following query used on one of my datasets in Athena.

CREATE TABLE clean_table
WITH (format='Parquet', external_location='s3://test123data') AS
SELECT npi,
         provider_last_name,
         provider_first_name,

    CASE
    WHEN REPLACE(num_entitlement_medicare_medicaid,',', '') ='' THEN
    null
    ELSE CAST(REPLACE(num_entitlement_medicare_medicaid,',', '') AS DECIMAL)
    END AS medicare_medicaid_entitlement,
    CASE
    WHEN REPLACE(total_submitted_charge_amount,',', '') ='' THEN
    null
    ELSE CAST(REPLACE(num_entitlement_medicare_medicaid,',', '') AS DECIMAL)
    END AS total_submitted_charge_amount
FROM cmsaggregatepayment2017

Unfortunately after I run this query I get an error as below:

GENERIC_INTERNAL_ERROR: Path is not absolute: s3://test123data. You may need to manually clean the data at location 's3://aws-athena-query-results-785609744360-us-east-1/Unsaved/2019/12/15/tables/03d3cedf-0101-43cb-91fd-cc8070db0e37' before retrying. Athena will not delete data in your account.

Can someone walk me through how to handle this? What do I have to do on the bucket since it is empty

回答1:

It appears that this message is referring to the Query result location in which Athena automatically stores the output of your queries.

This is useful for running queries on the results of queries, or for simply having a copy of the query output.

See: Working with Query Results, Output Files, and Query History - Amazon Athena

You can specify a new output location by clicking the settings link in the Athena console and then providing a Query result location path, such as: s3://my-bucket/athena-output/

I'm not sure what is causing your specific error, but make sure you append a trailing / to the location. You might also want to create a new bucket for that output.
