The short answer is there is no easy way to determine what file/directory a waiter may be related. Generally, it is not necessary to know the file/directory since a properly sized/configured cluster should not have long waiters occurring, unless there is some type of failure in the cluster. If you were to capture sufficient information across the cluster you might be able to work out the file/directory involved in a long waiter but it would take either trace, or combing through lots of internal data structures.
It would be helpful to know more details about your cluster to provide suggestions for what may be causing the long waiters. I presume you are seeing them on a regular basis and would like to understand why they are occurring.
