Hi,
I have created a external table which refers to a parquet format file. while trying to fire a select query it is giving me below error:

[Vertica]VJDBC ERROR: Cannot expand glob pattern due to error: Access Denied [SQL State=22023, DB Errorcode=7160]
1 statement failed
Where as I am able to list the bucket from cli.

Have created the location and provided the permission as well .
Have followed the steps descried in the below link:
https://www.vertica.com/docs/9.0.x/HTML/index.htm#Authoring/Eon/CreatingExternalTablesFromS3.htm

below is my table creation script:

    The response say Access Denied. Are you able to access the file in the bucket using the access key that is configured in Vertica? Did you set the session AWS security parameters, e.g.: ALTER SESSION SET AWSAuth='ID:secret';

  • mt_25mt_25 Registered User

    yes, Have executed below statements:
    ALTER SESSION SET AWSAuth='ID:*******';
    SELECT AWS_SET_CONFIG('aws_id', '*****');
    SELECT AWS_SET_CONFIG('aws_secret', '***);

    I am able to access the bucket from vertica as I was successfully able to load the data into vertica managed table via copy command.

  • Bryan_HBryan_H Employee, Registered User ✭✭

    So COPY works but not CREATE EXTERNAL TABLE AS COPY?
    The AWS_SET_CONFIG function is no longer recommended in 9.2. You should only use ALTER SESSION SET AWSAuth = 'aws_id:aws_secret'. See the latest doc at https://www.vertica.com/docs/9.2.x/HTML/Content/Authoring/Eon/CreatingExternalTablesFromS3.htm
    You may need to log out or disconnect to clear the session settings, then try to connect again with new session.

    thanks after reconnecting, it worked and yes with** ALTER SESSION SET AWSAuth = 'aws_id:aws_secret**' it is working fine now :) thanks for your quick response.
    Though it is giving a different error now but looks it is something to do with the data in parquet file.
    [Vertica]VJDBC ERROR: Datatype mismatch: column 6 in the parquet source [s3://mybucket/1_fact_rating_quarter_hour_nielsen/reporting_year=2018/reporting_month=1/market_code=101/rating_stream_int=5/part-00121-e8ac2dc7-39c3-4da2-8451-ffa7238448cb.c000.snappy.parquet] has type INT64, expected float [SQL State=22V24, DB Errorcode=7247]

    This seems to be your column 6:

    hh_impression float,

    .. as from the create external table common.test2 statement you sent above.

    The way I read it, in the Parquet file we have a format for a 64 bit integer, while you are declaring a float as a data type.

    Try to drop the table common.test2 and re-create it with:

    hh_impression int,

    instead ...

    happy playing ...
