balancer
Contents
Definition
Triggers the cluster Balancer. Returns true if the Balancer is running and is able to tell Region Servers to unassign all Regions to balance (the re-assignment itself is async). Otherwise returns false — in most cases, when some Regions are in transition (the input parameter force can be used to force the command in such cases).

CAUTION
For experts only. Forcing a balance may do more damage than repair if Regions assignment is corrupted.
