------------------------------------
Summary: All tasks finish but spark job does not conclude. Forever
waits for [DONE]
Key: SPARK-37976
URL: https://issues.apache.org/jira/browse/SPARK-37976
Project: Spark
Issue Type: Question
Components: PySpark
Affects Versions: 3.1.0
Reporter: Nitin Siwach
I am using the following command to submit a spark job: ```spark-submit
--master yarn --conf
"spark.jars.packages=com.microsoft.azure:synapseml_2.12:0.9.4" --conf
"spark.jars.repositories=https://mmlspark.azureedge.net/maven"; --conf
"spark.hadoop.fs.gs.implicit.dir.rep
air.enable=false"
--py-files=gs://monsoon-credittech.appspot.com/monsoon_spark/src.zip
gs://monsoon-credittech.appspot.com/monsoon_spark/custom_estimator.py
train_evaluate_cv --data-path
gs://monsoon-credittech.appspot.com/mar19/training_data.csv
--index hash_CR_ACCOUNT_NBR --label flag__6_months --save-results --nrows
100000 --evaluate --run-id run_ss_02```
Everything in the code finishes. I have {{print('savedddd'); print(scores)}} as
the ultimate last line of my code and it executes as well. All the activity on
all nodes goes to 0. Yet the job does not conclude. My shell prints
```{{{}22/01/13 19:29:15 INFO org.sparkproject.jetty.server.AbstractConnector:
Stopped Spark@a69cfdd\{HTTP/1.1, (http/1.1)}{0.0.0.0:0}```{}}} and that's it.
The job constantly shows as running and I have to manually cancel it.
Providing the output of ```jstack```. hoping it helps:
