> Create command to dump stack for FATE operation
> -----------------------------------------------
>
> Key: ACCUMULO-4152
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4152
> Project: Accumulo
> Issue Type: Improvement
> Reporter: Keith Turner
> Fix For: 1.8.0
>
>
> Each FATE operation has an associated stack of serialized java objects in
> zookeeper. It would be nice to be able to see the contents of these objects.
> One possible way to do this is to serialize each object on the stack as json
> and print out the json. Using json avoids implementing a useful toString
> method for each type of fate object.
