Zeppelin ClassNotFoundException

Tin6 — Mon, 19 Aug 2019 11:35:47 GMT

Hi Folks,

I'm going through the tutorial for hdp 2.5.0

In the following lab I'm encountering issues with http://hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/#step4.2

I'm getting class not found exception (see code below) which I have no clue how to solve! (default setting in the interpreter menu throws a file not found notification when I try to save the default settings) see attached picture.

Any help would be appreciated thanks 🙂

I can't get the interpreter to run in lab 5 either

%jbdc (hive)
SELECT * FROM riskfactor

prefix not found

Answering my own question!

In the following post I found my answer https://community.hortonworks.com/questions/56113/trying-to-create-phoenix-interpreter-using-jdbc-in.html

I created a new "test jdbc interpreter" left every setting default but added the following dependancies below. My newly created interpreter works but the default %jdbc interpreter still faults with the path error as in the attached picture.

org.apache.hive:hive-jdbc:0.14.0 org.apache.hadoop:hadoop-common:2.6.0

Many thanks!
