Hello everyone,
I have got some trouble using the REST API of Zeppelin. I have a PHP
application via which I am creating a paragraph in a notebook and later in
the same script trying to run that paragraph.
The new paragraph created has this text:
"%sql select date_time from table_name"
Now the paragraph is successfully created and also the running that
paragraph returns : {"status":"OK"}
But this error pops up when the job is run from the PHP application
org.codehaus.janino.JaninoRuntimeException: Class 'org.apache.spark.sql.
catalyst.expressions.codegen.GeneratedClass' was loaded through a different
loader

ERROR
However the pressing the "run" button for the same paragraph which I
created from PHP aplication gives the correct output that is a selected
column from the table.
Kindly help me resolving this error.
