            Error while running query on Impala with Superset
            Asked 2020-May-14 at 16:56

            I'm trying to connect impala to superset, and when I test the connection prints: "Seems OK!", and when I try to see databases on impala with the SQL Editor in the left side it shows all databases without problems.

            Preview of Databases/Tables

            But when i write a query and click on "Run Query", it gives the error: "Could not start SASL: b'Error in sasl_client_start (-1) SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Ticket expired)'"

            Error running query

            I'm running superset with SSL and in production mode (with Gunicorn) and Impala with SSL in a Kerberized Hadoop Cluster, and my impala database config is:

            I was able to fix this error doing this steps:

            1 - Created service user for celery-worker, created a kerberos ticket for him and created a crontab to renew the ticket.

            2 - Runned celery worker from this service user, instead running from root.

            3 - Killed an celery-worker that was running in another machine of my cluster

            4 - Restarted Impala and Superset

            I think this error ocurred because in some queries instead of use the celery worker in my superset machine, it was using the celery worker that was in another machine without a valid kerberos ticket. I could fix this error because when I was reading celery-worker log , it showed that a connection with the celery worker in other machine failed in a query running.

            QUESTION

            Ibis create impala table with pandas dataframe and get [Error 61] Connection refused
            Asked 2020-May-04 at 00:49

            After doing impyla sql statement, I convert the results into pandas dataframe format. But now I want to auto create a temporary table on impala using Apache Ibis to create table and load a dataframe into it. The following codes are divided into 3 phase:

            1. phase 1 creates a null table with user-defined schema
            2. phase 2 creates a table which schema and data are came from another table
            3. phase 3 is the main part I want to do (suppose the dataframe is given)

            and error code shows below. Does anyone know what happened it is? Cuz the configurations are the same, I don't know why it will get connection exception when doing phase 3.

            Thank you a lot !

            Solved. Our environment is CDH6.3.2 and I check the Namenode web ui port dfs.namenode.http-address on CM is 9870 instead of 50070. Change hdfs client connection conf. on the code above and it will work well
