---------------------------------------
Summary: Add StreamingQueryListener support to PySpark
Key: SPARK-30105
URL: https://issues.apache.org/jira/browse/SPARK-30105
Project: Spark
Issue Type: New Feature
Components: PySpark, Structured Streaming
Affects Versions: 3.0.0
Reporter: Abhijeet Prasad
Add support for StreamingQueryListener to PySpark.
Currently the `StreamingQueryListener` in Scala is implemented as an abstract
class, so we cannot use Python proxies (Py4j) to access it unless we create our
own custom Scala/Java wrapper.
[https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/streaming/StreamingQueryListener.scala]
This would be very useful in my personal case, I am building a library that
allows you to send Python errors to Sentry.io
[https://docs.sentry.io/platforms/python/pyspark/] and would like to hook onto
onQueryTerminated to send errors.
I can take this on if you point me in which direction to go, new to the
codebase so not quite sure what the process for porting Scala API -> PySpark
API changes usually look like.
