Hyukjin Kwon created SPARK-22043:
------------------------------------
Summary: Python profile, show_profiles() and dump_profiles(),
should throw an error with a better message
Key: SPARK-22043
URL: https://issues.apache.org/jira/browse/SPARK-22043
Project: Spark
Issue Type: Improvement
Components: PySpark
Affects Versions: 2.3.0
Reporter: Hyukjin Kwon
Priority: Trivial
I mistakenly missed {{spark.python.profile}} enabled today while profiling and
met this unfriendly messages:
{code}
>>> sc.show_profiles()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File ".../spark/python/pyspark/context.py", line 1000, in show_profiles
self.profiler_collector.show_profiles()
AttributeError: 'NoneType' object has no attribute 'show_profiles'
>>> sc.dump_profiles("/tmp/abc")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File ".../spark/python/pyspark/context.py", line 1005, in dump_profiles
self.profiler_collector.dump_profiles(path)
AttributeError: 'NoneType' object has no attribute 'dump_profiles'
{code}
It looks we should give better information that says {{spark.python.profile}}
should be enabled.
