Impala Pro Driver Issues - Java --- class jar files not found

repealp — Fri, 08 Nov 2024 08:59:05 GMT

Am trying to install Impala Pro access through DBvisualizer

but logon fails with Java error messages Java Class ....Jar not found

I have installed the Impala driver on the clients Virtual windows , it seems

to uld place the drivers etc in the download folder.

When I go into the DBVis Driver manager for the entry JDBC IMPALA

here is an error message "No driver classes fund check your artifact and jar files"

The drivers path is displayed as C;...Downloads/impala/JDBC41.jar (inactive).

My knowledge of Impala PRO and Java is very limited appreciate any tips !

Could it be that Downloads is not in the Java path ?

Thanks !

Peter

Hello-

Looks like you did not follow the setup instructions in https://docs.cloudera.com/documentation/other/connectors/impala-jdbc/2-6-23/Cloudera-JDBC-Driver-for-Impala-Install-Guide.pdf. Especially when it comes to referencing Driver Libraries, like on p.8 etc. Please re-visit the document and follow the steps to have the Driver Jar "visible" to the Windows applications.

HTH.
