Method Detail

newBuilder

public static org.apache.hadoop.hbase.client.BalanceResponse.Builder newBuilder()

Creates a new BalanceResponse.Builder

isBalancerRan

public boolean isBalancerRan()

Returns true if the balancer ran, otherwise false. The balancer may not run for a variety of reasons, such as: another balance is running, there are regions in transition, the cluster is in maintenance mode, etc.

getMovesCalculated

public int getMovesCalculated()

The number of moves calculated by the balancer if isBalancerRan() is true. This will be zero if no better balance could be found.

getMovesExecuted

public int getMovesExecuted()

The number of moves actually executed by the balancer if it ran. This will be zero if getMovesCalculated() is zero or if BalanceRequest.isDryRun() was true. It may also not be equal to getMovesCalculated() if the balancer was interrupted midway through executing the moves due to max run time.
