[jira] [Created] (SAMZA-96) Improve DaemonThreadFactory to specify thread name, use that capability

Jakob Homan created SAMZA-96:
--------------------------------

             Summary: Improve DaemonThreadFactory to specify thread name, use that capability
                 Key: SAMZA-96
                 URL: https://issues.apache.org/jira/browse/SAMZA-96
             Project: Samza
          Issue Type: Bug
    Affects Versions: 0.7.0
            Reporter: Jakob Homan
            Priority: Trivial
             Fix For: 0.7.0


The DaemonThreadFactory class is used by  the JvmMetrics (line 42) and MetricsSnapshotReporter (line 60) classes to create these classes' respective threads, but it does not take any way to name the threads that the factory creates.  When these threads are running and inspected in, say VisualVM, they're boringly named Thread-6 or whatever.

It'd be better to pass the factory a name or naming function and then name the metrics threads so they're easier to work with from debuggers.
