Jose Torres created SPARK-24039:
-----------------------------------
Summary: remove restarting iterators hack
Key: SPARK-24039
URL: https://issues.apache.org/jira/browse/SPARK-24039
Project: Spark
Issue Type: Sub-task
Components: Structured Streaming
Affects Versions: 2.4.0
Reporter: Jose Torres
Currently, continuous processing execution calls next() to restart the query
iterator after it returns false. This doesn't work for complex RDDs - we need
to call compute() instead.
This isn't refactoring-only; changes will be required to keep the reader from
starting over in each compute() call.
