----------------------------------------
Summary: Make streaming PySpark ML tests more robust using
termination conditions
Key: SPARK-9805
URL: https://issues.apache.org/jira/browse/SPARK-9805
Project: Spark
Issue Type: Test
Components: MLlib, PySpark, Streaming
Affects Versions: 1.5.0
Reporter: Joseph K. Bradley
Assignee: Joseph K. Bradley
Recently, PySpark ML streaming tests have been flaky, most likely because of
the batches not being processed in time. Proposal: Replace the use of
_ssc_wait (which waits for a fixed amount of time) with a method which waits
for a fixed amount of time but can terminate early based on a termination
condition method. With this, we can extend the waiting period (to make tests
less flaky) but also stop early when possible (making tests faster on average).
