I recently switched over from using a PC to a Mac and now for whatever reason one of my Impala drivers that worked fine is no longer found when run in Python. I keep receiving this error every time I run the script : "java.lang.RuntimeException: Class com.cloudera.impala.jdbc41.Driver not found". Please see code snippet for my connection below.

c = jaydebeapi.connect (jclassname='com.cloudera.impala.jdbc41.Driver', url='jdbc:impala://cloudera-impala-proxy.live.bi.xxx/;AuthMech=3;ssl=1;', driver_args=['xxx', self.dwh_password], jars='/Users/xxx/Desktop/ImpalaJDBC41 2.jar')

Any help or suggestions are appreciated, I feel like I'm going crazy trying to get this to work.

Did you check do you have the ImpalaJDBC***.jar in your new machine. Please check properly weather it's available at classpath/build path or not.

Edit: You can use hive jdbc jar as well to connect with impala , just use the port of impala rather hive in jdbc url.

Looking at this error means your jar is corrupt. First check your impalaJDBC jar

java -jar ImpalaJDBC<version>.jar

If it gives you error that means your jar is corrupt.

Download the correct jar from cloudera
