Document

Creates a single-threaded executor that can schedule commands to run after a given delay, or to execute periodically.

Usage

From source file:org.apache.hadoop.hbase.master.assignment.TestAssignmentManager.java

@Before
public void setUp() throws Exception {
    UTIL = new HBaseTestingUtility();
    this.executor = Executors.newSingleThreadScheduledExecutor();
    setupConfiguration(UTIL.getConfiguration());
    master = new MockMasterServices(UTIL.getConfiguration(), this.regionsToRegionServers);
    rsDispatcher = new MockRSProcedureDispatcher(master);
    master.start(NSERVERS, rsDispatcher);
    am = master.getAssignmentManager();/*from   ww w  .  ja va  2 s  .  c  om*/
    assignProcMetrics = am.getAssignmentManagerMetrics().getAssignProcMetrics();
    unassignProcMetrics = am.getAssignmentManagerMetrics().getUnassignProcMetrics();
    setUpMeta();
