---------------------------------------

             Summary: Ensure that all create threads have a proper name
                 Key: FLINK-5062
                 URL: https://issues.apache.org/jira/browse/FLINK-5062
             Project: Flink
          Issue Type: Improvement
    Affects Versions: 1.1.3
            Reporter: Chesnay Schepler
             Fix For: 1.2.0


There are a few places where we create a Thread without giving it an explicit name. This can make debugging harder than necessary.

I've made a sweep some time ago and found the following culprits:
* ProcessShutDownThread, used in the shutdown of TM/JM
* StreamPrinter, used by python operators
* SplitReader, used ContinuousFileReaderOperator
* CallExecute, used in DataStreamUtils#collect

In addition we should check for usages of ExecutorServices that don't provide an explicit ThreadFactory (which would allow explicit names).

I pushed a hotfix today which resolved another occurrence in the MetricRegistry.
