1. A FUSE object storage device of a cluster file system, comprising: a memory; and at least one processing device coupled to a memory, configured to: communicate with at least one object storage server of the cluster file system; and provide an interface between said cluster file system and a parallel log structured file system having a FUSE implementation and comprising a burst buffer appliance, wherein said burst buffer appliance comprises a high-speed memory that provides a buffer between a plurality of clients on one or more compute nodes and said cluster file system for storing bursty data associated with input-output (JO) operations, wherein said interface maps, using said FUSE object storage device associated with said at least one object storage server, one or more file-based operations of said FUSE implementation to one or more object-based operations of said cluster file system by creating a plurality of files, in a FUSE file system, for a plurality of objects of said FUSE object storage device.
