Class ProcedureSyncWait

java.lang.Object

org.apache.hadoop.hbase.master.procedure.ProcedureSyncWait

@Private
@Evolving
public final class ProcedureSyncWait
extends Object

Helper to synchronously wait on conditions. This will be removed in the future (mainly when the AssignmentManager will be replaced with a Procedure version) by using ProcedureYieldException, and the queue will handle waiting and scheduling based on events.
