Hi,
I am trying to use oracle jdbc to read oracle database table. I have added
below property in custom zeppelin-env:
SPARK_SUBMIT_OPTIONS="--jars /my/path/to/ojdbc8.jar"
But
val df = spark.read.format("jdbc").option("url", "jdbc:oracle:thin:@
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=10.9.44.99)(PORT=1521))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=
myservice.mydns.com)))").option("user","myuser").option("password","mypassword").option("driver",
"oracle.jdbc.driver.OracleDriver").option("dbtable",
"myuser.mytable").load()
throws:
java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver at

How to make livy2.spark interpreter find ojdbc8.jar? Thanks.
