[GitHub] [beam] kennknowles opened a new issue, #18238: Python word count with DirectRunner gets stuck during application termination on Windows

[GitBox <gi...@apache.org>]

kennknowles opened a new issue, #18238:
URL: https://github.com/apache/beam/issues/18238

   Using virtualenv 15 **** python 2.7.13 **** pip 9.0.1 on Windows 2016
   
   Example logs from DirectRunner:
   ```
   
   (beamRC2)PS C:\Users\lcwik\.virtualenvs\beamRC2> python -m apache_beam.examples.wordcount --input ".\input\*"
   --output l
   ocal_counts
   No handlers could be found for logger "oauth2client.contrib.multistore_file"
   INFO:root:Missing
   pipeline option (runner). Executing pipeline using the default runner: DirectRunner.
   INFO:root:Running
   pipeline with DirectRunner.
   
   ```
   
   
   Application gets stuck here, pressing ctrl-z gets it unstuck and the remainder below is logged
   ```
   
   INFO:root:Starting finalize_write threads with num_shards: 1, batches: 1, num_threads: 1
   INFO:root:Renamed
   1 shards in 0.14 seconds.
   INFO:root:number of empty lines: 47851
   INFO:root:average word length: 4
   
   ```
   
   
   Output is correct, so it seems as though the bug is somewhere in shutdown.
   Happens when using a local or gs path with the DirectRunner. Enabling DEBUG logging did not add any additional details.
