I just tested the storm compatibility code, and stumbled across the
following issues in the logs:
1) Multiple SLF4J bindings. If Storm brings its own one, we may need to
define an exclusion in the storm dependencies.
```
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/home/cicero/.m2/repository/ch/qos/logback/logback-classic/1.0.13/logback-classic-1.0.13.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in
[jar:file:/home/cicero/.m2/repository/org/slf4j/slf4j-log4j12/1.7.7/slf4j-log4j12-1.7.7.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an
explanation.
```
2) Improper Task life cycle. The logs below indicate that the JobManager
and TaskManager are in some way killed/removed before the tasks are properly
removed and before the client learns about the JobStatus.
I am a bit puzzled how you actually manage to provoke this ;-)
