I am working on Pentaho Data Integration tool version 5.2. I am trying to connect to data base using 'Table Input' step. but when I test the connection in this step it is giving me the below error message. I am able to connect to DB using the MySQL workbench. I have placed the 'mysql-connector-java-5.1.38-bin' file in the libext forlder.
do I need to downgrade my connector jar file? if yes my SQL version is 5.6 so can some one let me know the compatible connector jar version for this SQL Server version?

I have fixed the issue. the useCursorFetch was set to true which I have changed to false in the Options menu in the left side panel of Data Base connection.
