RuntimeException: Inconsistent state

[Jonathan Herzig]

Hi, i keep getting these kind of exceptions when i'm running a jaql
script. My setup is a 5 machine cluster. The output data seems to be
created, although i can't say if it's valid.

What is the source of this exception? Does it affect the success of
map/reduce tasks?

Thanks,
Jonathan

The exception:

java.lang.RuntimeException: Inconsistent state!!! JVM Manager reached
an unstable state while reaping a JVM for task:

Not sure what the exact cause is, but a Google search with bits of your exception show that Hadoop
had this issue in older versions ( <= 0.19 ?).
