  I am just sharing the relevant part of the linked docs, as they contain the instructions on how to enable the hbase balancer via hbase shell:   Load Balancer It is assumed that the Region Load Balancer is disabled while the graceful_stop script runs (otherwise the balancer and the decommission script will end up fighting over region deployments). Use the shell to disable the balancer: hbase(main):001:0> balance_switch false true 0 row(s) in 0.3590 seconds This turns the balancer OFF. To reenable, do: hbase(main):001:0> balance_switch true false 0 row(s) in 0.3590 seconds The graceful_stop will check the balancer and if enabled, will turn it off before it goes to work. If it exits prematurely because of error, it will not have reset the balancer. Hence, it is better to manage the balancer apart from graceful_stopreenabling it after you are done w/ graceful_stop. ... View more
