> This is to verify:
> * Evict RAM_DISK block with open handle should fall back to DISK.
> * Delete RAM_DISK block (persisted) with open handle should mark the block to be deleted
upon handle close. 
> Simply open handle to file in DFS name space won't work as expected. We need a local
FS file handle to the block file. The only meaningful case is for Short Circuit Read. This
JIRA is to validate/enable the two cases with SCR enabled MiniDFSCluster.
