Hi Jeff,

Sorry for the late response.

I ran yarn-cluster mode with this setup

%spark2.conf

master yarn
spark.submit.deployMode cluster
zeppelin.pyspark.python /home/mansop/anaconda2/bin/python
spark.driver.memory 10g

I added ` log4j.logger.org.apache.zeppelin.interpreter=DEBUG` to the ` 
log4j_yarn_cluster.properties` file but nothing has changed, in fact the ` 
zeppelin-interpreter-spark2-mansop-root-zama-mlx.mlx.log` file is not updated 
after running my notes

This code works

%pyspark

print("Hello world!")

However this one does not work:

%pyspark

a = "bigword"
aList = []
for i in range(1000):
    aList.append(i**i*a)
#print aList

for word in aList:
    print word

which means I am still getting org.apache.thrift.transport.TTransportException 
at 
org.apache.thrift.transport.TIOStreamTransport.read(TIOStreamTransport.java:132)
 at org.apache.thrift.transport.TTransport.readAll(TTransport.java:86)

and spark logs says:
ERROR [2019-10-09 12:15:16,454] ({SIGTERM handler} 
SignalUtils.scala[apply$mcZ$sp]:43) - RECEIVED SIGNAL TERM
…

org.apache.hadoop.yarn.exceptions.ApplicationAttemptNotFoundException:

Any idea?

Then it looks like something wrong with the python process. Do you run it in 
yarn-cluster mode or yarn-client mode ?
Try to add the following line to log4j.properties for yarn-client mode or 
log4j_yarn_cluster.properties for yarn-cluster mode

log4j.logger.org.apache.zeppelin.interpreter=DEBUG

And try it again, this time you will get more log info, I suspect the python 
process fail to start

Yes, I have successfully ran few simple scala codes using %spark interpreter in 
zeppelin.

What should I do next?

It looks like you are using pyspark, could you try just start scala spark 
interpreter via `%spark` ? First let's figure out whether it is related with 
pyspark.

Dear Zeppelin community,

I would like to ask for advice in regards an error I am having with thrift.

I am getting quite a lot of these errors while running my notebooks
