> 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.
