----------------------------------
> Streaming StatefulNetworkWordCount example hangs
> ------------------------------------------------
>
> Key: SPARK-5252
> URL: https://issues.apache.org/jira/browse/SPARK-5252
> Project: Spark
> Issue Type: Bug
> Components: Examples, PySpark, Streaming
> Affects Versions: 1.2.0
> Environment: Ubuntu Linux
> Reporter: Lutz Buech
> Attachments: debug.txt
>
>
> Running the stateful network word count example in Python (on one local node):
> https://github.com/apache/spark/blob/master/examples/src/main/python/streaming/stateful_network_wordcount.py
> At the beginning, when no data is streamed, empty status outputs are
> generated, only decorated by the current Time, e.g.:
> -------------------------------------------
> Time: 2015-01-14 17:58:20
> -------------------------------------------
> -------------------------------------------
> Time: 2015-01-14 17:58:21
> -------------------------------------------
> As soon as I stream some data via netcat, no new status updates will show.
> Instead, one line saying
> [Stage <number>:====================================================>
> (2 + 0) / 3]
> where <number> is some integer number, e.g. 132. There is no further output
> on stdout.
