I am new to zeppelin and trying to setup the zeppelin on my system. Till now I have done the following steps:
- Downloaded zeppelin from here
- Setup the JAVA_HOME at my system environment variable.
- Goto zeppelin-0.7.3-bin-all\bin and ran zeppelin.cmd
- Able to see zeppelin-ui at http://localhost:8090
When I am trying to run load data into table
program mentioned in zeppelin tutotial -> Basic Features(spark) it is throwing following error
java.lang.NullPointerException

The above mentioned error log i am able to see in output inside zeppelin-ui at the same time my console (cmd) shows following error:

Is there anything that I am missing or anything to do with spark? Because I am assuming zeppelin will take care of spark and we do not have to setup the spark. Thanks in advance for helping me!
