Íñigo Goiri commented on HDFS-13909:
------------------------------------
True, the parameter is a CacheDirectiveInfo not a path.
In any case, modifying RemoteParam to store a CacheDirectiveInfo is
straightforward.
I'm not sure you need changes in the invoke path, just in RemoteParam and
RemoteMethod.
I think this is better as it follows an extensible approach where RemoteParam
represents a parameter that is modified depending on the subcluster we run on.
