[jira] [Updated] (SPARK-26113) TypeError: object of type 'NoneType'
has no len() in authenticate_and_accum_updates of pyspark/accumulators.py
[ https://issues.apache.org/jira/browse/SPARK-26113?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sai Varun Reddy Daram updated SPARK-26113:
------------------------------------------
Description:
Machine OS: Ubuntu 16.04.
Kubernetes: Minikube
Kubernetes Version: 1.10.0
Spark Kubernetes Image: pyspark ( at docker hub: saivarunr/spark-py:2.4 ) built using standard spark docker build.sh file.
Steps to replicate:
1) Create a spark Session:
{code:java}
// spark_session=SparkSession.builder.master('k8s://https://192.168.99.100:8443').config('spark.executor.instances','1').config('spark.kubernetes.container.image','saivarunr/spark-py:2.4').getOrCreate()
{code}
2) Create a sample DataFrame
{code:java}
// df=spark_session.createDataFrame([{'a':1}])
{code}
3) Do some operation on this dataframe
{code:java}
// df.count(){code}
I get this output.
{code:java}
// Exception happened during processing of request from ('127.0.0.1', 38690)
Traceback (most recent call last):
File "/usr/lib/python3.6/socketserver.py", line 317, in _handle_request_noblock
self.process_request(request, client_address)
File "/usr/lib/python3.6/socketserver.py", line 348, in process_request
self.finish_request(request, client_address)
File "/usr/lib/python3.6/socketserver.py", line 361, in finish_request
self.RequestHandlerClass(request, client_address, self)
File "/usr/lib/python3.6/socketserver.py", line 721, in __init__
self.handle()
File "/spark-2.4.0-bin-hadoop2.7/python/lib/pyspark.zip/pyspark/accumulators.py", line 266, in handle
poll(authenticate_and_accum_updates)
File "/spark-2.4.0-bin-hadoop2.7/python/lib/pyspark.zip/pyspark/accumulators.py", line 241, in poll
if func():
File "/spark-2.4.0-bin-hadoop2.7/python/lib/pyspark.zip/pyspark/accumulators.py", line 254, in authenticate_and_accum_updates
received_token = self.rfile.read(len(auth_token))
TypeError: object of type 'NoneType' has no len()
{code}
4) Repeat above step; it won't show the error.
But now close the session, kill the python terminal or process. and try again, the same happens.
Something related to https://issues.apache.org/jira/browse/SPARK-26019 ?
