        I have implemented this feature. The reporting is not as good as that provided by the JVM (it does not report on locks held). However, it is much easier to request this thread dump than it is to have someone log into the OS and use jstack.

        The feature can be invoked using an incantation similar to the following.

        http://localhost:8080/bigdata/status?threadDump
