fid stat

Displays statistics for MapR Database or file system components that are identified by an FID.

Only the root user and the MAPR_USER user (user name under which MapR services runs) have permissions to run this command.

Note: This command is similar to the UNIX stat command.


maprcli fid stat
   [ -cluster <cluster name> ]
   -fid <file identifier for the element>


Parameter Description
