> Storing arbitrary objects in the configuration has been discussed before in HADOOP-449 and HADOOP-1873. Although enabling such functionality has the risk of encouraging people to put big binary objects in the configuration, for some use cases passing objects to tasks is absolutely necessary. 
> This issue will track the implementation of a Stringifier interface which stringifies and destringifies objects. Using this implementation, developers can store objects in the configuration and restore them later. 
> Any thoughts ?
