livy-on-spark3 interpreter died

[#1]

Hello,

trying to setup zeppelin + livy-on-spark3.

Livy-on-spark2 is up and r

spark3.sql runs fine, any spark3.pyspark code returns error "Interpreter died:".

What could be wrong?

i have also encountered this weird situation interpreter died when using livy pyspark on spark3. I have lost for 2 days debugging this errors and i've found out that we need to:

1. In the "Spark 3" service on Cloudera manager portal, set spark pyspark python and python driver executable files configuration in the section "Spark 3 Client Advanced Configuration Snippet (Safety Valve) for spark3-conf/spark-defaults.conf" as below:

spark.pyspark.driver.python=/usr/bin/python3
spark.pyspark.python=/usr/bin/python3

2. Restart "livy for Spark 3" service on cloudera manager.

3. Restart the Zeppelin Livy Interpreter.

=> After being restarted, the zeppelin's livy interpreter on Spark 3 can execute %pyspark interpreter.

=> Note that, the python version to work with livy spark 3 on zeppelin must be less than or equal 3.7. otherwise it will generate error "required field "type_ignores" missing from Module" when executing pyspark script on Zeppelin.

Hi Team,

Livy3 with Zeppelin Integration is not yet supported.

To use Spark3, you need to install python3 and needs to add the following parameters:

PYSPARK3_PYTHON

spark.yarn.appMasterEnv.PYSPARK3_PYTHON
