             Summary: Names of temporary files created by interactive runner include characters invalid on some platforms.
                 Key: BEAM-9687
                 URL: https://issues.apache.org/jira/browse/BEAM-9687
             Project: Beam
          Issue Type: Sub-task
          Components: sdk-py-core
            Reporter: Valentyn Tymofieiev
            Assignee: Sam Rohde


Temporary files created by interactive runner in streaming scenarios include pipe '|' characters, which are not allowed in filenames on Windows platform. This causes test failures on a Windows platform:

====================================
python setup.py nosetests --tests apache_beam/runners/interactive/pipeline_instrument_test.py:PipelineInstrumentTest.test_instrument_example_unbounded_pipeline_to_multiple_read_cache

======================================================================
ERROR: Tests that the instrumenter works for multiple unbounded sources.
