Example 11 with HBaseFsck

use of org.apache.hadoop.hbase.util.HBaseFsck in project hbase by apache.

the class TestMetaWithReplicas method testHBaseFsckWithExcessMetaReplicas.

@Test
public void testHBaseFsckWithExcessMetaReplicas() throws Exception {
    // Create a meta replica (this will be the 4th one) and assign it
    HRegionInfo h = RegionReplicaUtil.getRegionInfoForReplica(HRegionInfo.FIRST_META_REGIONINFO, 3);
    // create in-memory state otherwise master won't assign
    TEST_UTIL.getMiniHBaseCluster().getMaster().getAssignmentManager().getRegionStates().createRegionState(h);
    TEST_UTIL.assignRegion(h);
    HBaseFsckRepair.waitUntilAssigned(TEST_UTIL.getAdmin(), h);
