### What changes were proposed in this pull request? Test is flaky (https://github.com/apache/spark/runs/3109815586): ``` Traceback (most recent call last): File "/__w/spark/spark/python/pyspark/mllib/tests/test_streaming_algorithms.py", line 391, in test_parameter_convergence eventually(condition, catch_assertions=True) File "/__w/spark/spark/python/pyspark/testing/utils.py", line 91, in eventually raise lastValue File "/__w/spark/spark/python/pyspark/testing/utils.py", line 82, in eventually lastValue = condition() File "/__w/spark/spark/python/pyspark/mllib/tests/test_streaming_algorithms.py", line 387, in condition self.assertEqual(len(model_weights), len(batches)) AssertionError: 9 != 10 ``` Should probably increase timeout ### Why are the changes needed? To avoid flakiness in the test. ### Does this PR introduce _any_ user-facing change? Nope, dev-only. ### How was this patch tested? CI should test it out. Closes #33427 from HyukjinKwon/SPARK-36216.

Apache Spark
Spark is a unified analytics engine for large-scale data processing. It provides high-level APIs in Scala, Java, Python, and R, and an optimized engine that supports general computation graphs for data analysis. It also supports a rich set of higher-level tools including Spark SQL for SQL and DataFrames, MLlib for machine learning, GraphX for graph processing, and Structured Streaming for stream processing.
Online Documentation
You can find the latest Spark documentation, including a programming guide, on the project web page
Python Packaging
This README file only contains basic information related to pip installed PySpark. This packaging is currently experimental and may change in future versions (although we will do our best to keep compatibility). Using PySpark requires the Spark JARs, and if you are building this from source please see the builder instructions at "Building Spark".
The Python packaging for Spark is not intended to replace all of the other use cases. This Python packaged version of Spark is suitable for interacting with an existing cluster (be it Spark standalone, YARN, or Mesos) - but does not contain the tools required to set up your own standalone Spark cluster. You can download the full version of Spark from the Apache Spark downloads page.
NOTE: If you are using this with a Spark standalone cluster you must ensure that the version (including minor version) matches or you may experience odd errors.
Python Requirements
At its core PySpark depends on Py4J, but some additional sub-packages have their own extra requirements for some features (including numpy, pandas, and pyarrow).
