Commands for managing Router-based federation.

The usage is as follows:

$ hdfs dfsrouteradmin
    [-add <source> <nameservice1, nameservice2, ...> <destination> [-readonly] [-faulttolerant] [-order HASH|LOCAL|RANDOM|HASH_ALL] -owner <owner> -group <group> -mode <mode>]
    [-update <source> [<nameservice1, nameservice2, ...> <destination>] [-readonly true|false] [-faulttolerant true|false] [-order HASH|LOCAL|RANDOM|HASH_ALL] -owner <owner> -group <group> -mode <mode>]
    [-rm <source>]
    [-ls [-d] <path>]
    [-getDestination <path>]
    [-setQuota <path> -nsQuota <nsQuota> -ssQuota <quota in bytes or quota size string>]
    [-setStorageTypeQuota <path> -storageType <storage type> <quota in bytes or quota size string>]
    [-clrQuota <path>]
    [-clrStorageTypeQuota <path>]
    [-safemode enter | leave | get]
    [-nameservice disable | enable <nameservice>]
    [-getDisabledNameservices]
    [-refresh]
    [-refreshRouterArgs <host:ipc_port> <key> [arg1..argn]]
    [-refreshSuperUserGroupsConfiguration]

Arguments
-add source nameservices destination	Adds a mount table entry or update if it exists
-update source nameservices destination	Updates a mount table entry attributes
-rm source	Removes mount point of specified path
--ls [-d] path	Lists mount points under specified path. Specify `-d` parameter to get detailed listing
-getDestination path	Gets the subcluster where a file is or should be created
-setQuota path -nsQuota nsQuota -ssQuota ssQuota	Sets quota for specified path
-setStorageTypeQuota path -storageType storageType stQuota	Clears quota of given mount point
-clrQuota path	Sets storage type quota for specified path
-clrStorageTypeQuota path	Clears storage type quota of given mount point
-safemode enter leave get	Manually sets the router entering or leaving the safe mode. The option get will be used for verifying if the Router is in the safe mode state
-nameservice disable enable nameservice	Disables/enables a name service from the federation. If disabled, requests will not go to that name service
-getDisabledNameservices	Gets the name services that are disabled in the federation
-refresh	Updates mount table cache of the connected router
-refreshRouterArgs <host:ipc_port> <key> [arg1..argn]	Triggers a runtime-refresh of the resource specified by <key> on `host:ipc_port`. For example, to enable white list checking, you have to send a refresh command other than restart the router server
-refreshSuperUserGroupsConfiguration	Refreshes superuser proxy groups mappings on the router
