示例1: setUp

@Before
public void setUp() throws Exception {
conf = TEST_UTIL.getConfiguration();
conf.setInt("hfile.format.version", 3);
conf.set(HConstants.CRYPTO_KEYPROVIDER_CONF_KEY, KeyProviderForTesting.class.getName());
conf.set(HConstants.CRYPTO_MASTERKEY_NAME_CONF_KEY, "hbase");
// Create the test encryption key
SecureRandom rng = new SecureRandom();
byte[] keyBytes = new byte[AES.KEY_LENGTH];
rng.nextBytes(keyBytes);
String algorithm =
conf.get(HConstants.CRYPTO_KEY_ALGORITHM_CONF_KEY, HConstants.CIPHER_AES);
cfKey = new SecretKeySpec(keyBytes,algorithm);
// Start the minicluster
TEST_UTIL.startMiniCluster(3);
// Create the table
htd = new HTableDescriptor(TableName.valueOf("default", "TestHBaseFsckEncryption"));
HColumnDescriptor hcd = new HColumnDescriptor("cf");
hcd.setEncryptionType(algorithm);
