> HDFS caching currently is implemented using POSIX syscalls for checking ulimit and locking
pages of memory into the process's address space.  These POSIX syscalls do not exist on Windows.
 This issue will implement equivalent functionality so that Windows deployments can use Centralized
Cache Management.
