>                 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
>
> 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.
