示例1: corruptBlock

private void corruptBlock(MiniDFSCluster cluster, FileSystem fs, final Path fileName,
int dnIndex, ExtendedBlock block) throws IOException {
// corrupt the block on datanode dnIndex
// the indexes change once the nodes are restarted.
// But the datadirectory will not change
assertTrue(cluster.corruptReplica(dnIndex, block));

// Each datanode has multiple data dirs, check each
for (int dirIndex = 0; dirIndex < 2; dirIndex++) {
final String bpid = cluster.getNamesystem().getBlockPoolId();
File storageDir = cluster.getStorageDir(dnIndex, dirIndex);
File dataDir = MiniDFSCluster.getFinalizedDir(storageDir, bpid);
File scanLogFile = new File(dataDir, "dncp_block_verification.log.curr");
