Examples with BlockScanner org.apache.hadoop.hdfs.server.datanode.BlockScanner used on opensource projects

Example 1 with BlockScanner

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

the class TestFsVolumeList method setUp.

@Before
public void setUp() {
    dataset = mock(FsDatasetImpl.class);
    baseDir = new FileSystemTestHelper().getTestRootDir();
    Configuration blockScannerConf = new Configuration();
    blockScannerConf.setInt(DFSConfigKeys.DFS_DATANODE_SCAN_PERIOD_HOURS_KEY, -1);
    blockScanner = new BlockScanner(null, blockScannerConf);
}

Example 2 with BlockScanner

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

the class TestFsDatasetImpl method setUp.

@Before
public void setUp() throws IOException {

    storage = mock(DataStorage.class);
    this.conf = new Configuration();
    this.conf.setLong(DFS_DATANODE_SCAN_PERIOD_HOURS_KEY, 0);
    when(datanode.getConf()).thenReturn(conf);

    dataset = new FsDatasetImpl(datanode, storage, conf);
    for (String bpid : BLOCK_POOL_IDS) {
        dataset.addBlockPool(bpid, conf);
    }
