             Summary: SQL Client queries fails on select statement
                 Key: FLINK-22907
                 URL: https://issues.apache.org/jira/browse/FLINK-22907
             Project: Flink
          Issue Type: Bug
          Components: Table SQL / Client
    Affects Versions: 1.13.0
         Environment: python 3.7.6

JupyterLab

apache-flink==1.13.0
            Reporter: Ryan Darling
         Attachments: flink_sql_issue1.JPG

I have configured a Jupyter notebook to test flink jobs with the sql client. All of my source / sink table creation statements are successful but we are unable to query the created tables

In this scenario we are attempting to pull data from a kafka topic into a source table and if successful insert into a sink table and on to another kafka topic. 

We start the sql_client.sh passing the needed jar file locations (flink-sql-connector-kafka_2.11-1.13.0.jar, flink-table-planner_2.12-1.13.0.jar, flink-table-common-1.13.0.jar, flink-sql-avro-confluent-registry-1.13.0.jar, flink-table-planner-blink_2.12-1.13.0.jar)

Next we create the source table and point to a kafka topic that we know has avro data in it and registered schemas in the schema registry. 

CREATE TABLE avro_sources ( 
 prop_id INT,
 check_in_dt STRING,
 check_out_dt STRING,
 los INT,
 guests INT,
 rate_amt INT
 ) WITH (
 'connector' = 'kafka',
 'topic' = 'avro_rate',
 'properties.bootstrap.servers' = '<removed>',
 'key.format' = 'avro-confluent',
 'key.avro-confluent.schema-registry.url' = '<removed>',
 'key.fields' = 'prop_id',
 'value.format' = 'avro-confluent',
 'value.avro-confluent.schema-registry.url' = '<removed>',
 'value.fields-include' = 'ALL',
 'key.avro-confluent.schema-registry.subject' = 'avro_rate',
 'value.avro-confluent.schema-registry.subject' = 'avro_rate'
 )

 

At this point I want to see the data that has been pulled into the source table and I get the following error and are struggling to find a solution. I feel this could be a bug 

Flink SQL> select * from avro_sources;

[ERROR] Could not execute SQL statement. Reason:
java.lang.ClassCastException: org.codehaus.janino.CompilerFactory cannot be cast to org.codehaus.commons.compiler.ICompilerFactory

 

Any guidance on how I can resolve the bug or the problem would be appreciated.
