"Error rendering meta data"
I am trying to use the stream database node to import data from MySQL via JDBC, but unfortunately I get an error saying "Error rendering meta data" in the results tab. However in the data tab it seems like the import went well.
Thats the corresponding log entry:AM WARNING: Error creating renderer: java.lang.RuntimeException: Cannot retrieve data from database: com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.
Thanks in advance for your ideas.
