An error occurred while calling o101.getDynamicFrame.


i'm trying to do a job in glue who take data from a sql server in rds. I have a glue conection working fine when the job is made with no code. but when i use the same code in a notebook, i get this error:

Py4JJavaError: An error occurred while calling o101.getDynamicFrame. : The TCP/IP connection to the host, port 1433 has failed. Error: "connect timed out. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.".

my code below:

tb_node= glueContext.create_dynamic_frame_from_catalog(
    connection_type = "JDBC",
    url = "jdbc:sqlserver://blablabla",
    useConnectionProperties = "true",
    connectionName = "connection",
    database  = "db",
    table_name = "table",
    transformation_ctx = "tb_node", 
    useSparkDataSource = "True"

I've already tried the simpler way too:

tb_node= glueContext.create_dynamic_frame.from_catalog(

The same code but conecting in a S3 works fine!

dyf = glueContext.create_dynamic_frame.from_catalog(database='db_s3', table_name='s3_table')

What's wrong? The cloud security guy said all this TCP/IP properties by sql server its ok

In the notebook you have to add the same connection using the %connections magic

I have same situation. Can you please be more specific that where to add %connections?

  • you can put in any cell since it's a line magic, as long as they are executed before the code (they can share the cell with code or be on their own)
