pull an object from the cache by passing the cache paths directly
Get an object that has been distributed so as to be available for tasks in the current job.

Pulling an object from a given path.
Pulling an object from a given path.
We first try paths from:
Once a FSDataInputStream is successfully opened, the function f can do its job to recreate the object:
Distribute an object to be available for tasks in the current job using xstream
Distribute an object to be available for tasks in the current job using xstream
By default check right away if the object can be deserialised
Distribute an object to be available for tasks in the current job
Make a local filesystem path based on a 'tag' to temporarily store the serialised object.
Facilitate making an object available to all tasks (mappers, reducers, etc). Use XStream to serialise objects to XML strings and then send out via Hadoop's distributed cache. Two APIs are provided for pushing and pulling objects.
