Example 6 with FinalizedReplica

use of org.apache.hadoop.hdfs.server.datanode.FinalizedReplica in project hadoop by apache.

the class TestReplicaMap method testRemove.

@Test
public void testRemove() {

    try {
        map.remove(bpid, null);
        fail("Expected exception not thrown");
    } catch (IllegalArgumentException expected) {
    }
    // Test 2: remove failure - generation stamp mismatch 
    Block b = new Block(block);
    b.setGenerationStamp(0);
    assertNull(map.remove(bpid, b));
    // Test 3: remove failure - blockID mismatch
    b.setGenerationStamp(block.getGenerationStamp());
    b.setBlockId(0);
    assertNull(map.remove(bpid, b));
    // Test 4: remove success
    assertNotNull(map.remove(bpid, block));
    // Test 5: remove failure - invalid blockID
    assertNull(map.remove(bpid, 0));
    // Test 6: remove success
    map.add(bpid, new FinalizedReplica(block, null, null));
