receiving, using one or more processors, a request from the first slave node to access the network file system operated within the second operating environment, the request being based on a determination that the first slave node is operated within the first operating environment; and

responsive to receipt of the request from the first slave node, requesting a file from the network file system via a server-side runner module, the server-side runner module configured to communicate with the network file system on behalf of the first slave node in the second operating environment.

11. The computer-implemented method of claim 10 , wherein:

the second operating environment natively supports Hadoop; and

the cluster includes other slave nodes that operate in the second operating environment.

12. The computer-implemented method of claim 10 , further comprising:

receiving the file from the network file system via the server-side runner module; and

storing a copy of the file in a local file system that is operated within the first operating environment, the copy of the file being accessible to the first slave node operated within the first operating environment.

13. The computer-implemented method of claim 10 , further comprising:

sending a message to add the first slave node to the cluster, the message being sent to the server-side runner module, and

updating the network file system to indicate the first slave node as being added to the cluster.

14. The computer-implemented method of claim 10 , wherein:
