This is my code when run in pyspark env(version spark 3.1.2):

jdbcDF = spark.read \

.format("jdbc") \

.option("url", "jdbc:oracle:thin:@10.0.1.1:1521/sbank") \

.option("dbtable", "sa.a") \

.option("user", "g") \

.option("password", "zxc") \

.option("driver", "oracle.jdbc.driver.OracleDriver") \

.load()


But shows the announcement below as:


Py4JJavaError                             Traceback (most recent call last)
/tmp/ipykernel_29/4076487584.py in <module>

    328                     format(target_id, ".", name), value)

Py4JJavaError: An error occurred while calling o137.load

Can anyone help me to solve that? Thank you in advance.

I added ojdbc11.jar into jars forder of spark

I'm glad it works for you.

Thanks Kontext. I have tried to follow that web https://kontext.tech/article/1060/pyspark-read-data-from-oracle-database

That was successful.

Version of jdk is 1.8.0_352, open jdk 64-bit server VM.

All of logs I have shown above when I ran that statement code.

Hi Nguyen,

Welcome to Kontext!

For questions like this, you can publish in our Forums in future.

Have you followed this article? PySpark - Read Data from Oracle Database.

Can you please try ojdbc 8 instead of 11? ojdbc 11 requires JDK 11. Spark 3.1.2 can run on JDK 11 technically. What is your JDK version?

The error message is not detailed, can you paste the full error logs?
