> There are a number of commands in hbase-shell that return values that are
> undocumented or otherwise do not makes sense.
> The commands that will be addressed by this ticket were found in a survey of
> all the hbase shell commands,
> https://issues.apache.org/jira/browse/HBASE-24672.
> Subtasks:
> * Fix commands that return the number of printed lines (usually the number
> 1).
> ** Affected commands (culprits): is_disabled, balancer, normalize,
> normalizer_switch, normalizer_enabled, catalogjanitor_switch,
> catalogjanitor_enabled, cleaner_chore_switch, cleaner_chore_enabled,
> splitormerge_switch, splitormerge_enabled, clear_deadservers,
> clear_block_cache
> ** I am updating these 13 commands to either return a value that makes sense
> or return nil if a sensible return value doesn't exist.
> * Fix commands that return true or false as a String
> ** Affected commands (culprits): balance_switch, snapshot_cleanup_switch,
> enable_rpc_throttle, disable_rpc_throttle, enable_exceed_throttle_quota,
> disable_exceed_throttle_quota
> ** I am updating these 6 commands to return ruby's TrueClass or FalseClass
> rather than a String
