Examples of BlockTokenSecretManager

org.apache.hadoop.hdfs.security.token.block.BlockTokenSecretManager
BlockTokenSecretManager can be instantiated in 2 modes, master mode and slave mode. Master can generate new block keys and export block keys to slaves, while slaves can only import and use block keys received from master. Both master and slave can generate and verify block tokens. Typically, master mode is used by NN and slave mode is used by DN.
