Examples with TDelegationToken org.apache.accumulo.core.security.thrift.TDelegationToken used on opensource projects

Example 1 with TDelegationToken

use of org.apache.accumulo.core.security.thrift.TDelegationToken in project accumulo by apache.

the class SecurityOperationsImpl method getDelegationToken.

@Override
public DelegationToken getDelegationToken(DelegationTokenConfig cfg) throws AccumuloException, AccumuloSecurityException {
    final TDelegationTokenConfig tConfig;
    if (null != cfg) {
        tConfig = DelegationTokenConfigSerializer.serialize(cfg);
    } else {
        tConfig = new TDelegationTokenConfig();
    }
    TDelegationToken thriftToken;
    try {
        thriftToken = MasterClient.execute(context, new ClientExecReturn<TDelegationToken, Client>() {

            @Override
            public TDelegationToken execute(Client client) throws Exception {
                return client.getDelegationToken(Tracer.traceInfo(), context.rpcCreds(), tConfig);
            }
        });
    } catch (TableNotFoundException e) {
        // should never happen
        throw new AssertionError("Received TableNotFoundException on method which should not throw that exception", e);
    }
    AuthenticationTokenIdentifier identifier = new AuthenticationTokenIdentifier(thriftToken.getIdentifier());
    // Get the password out of the thrift delegation token
    return new DelegationTokenImpl(thriftToken.getPassword(), identifier);
}

Example 2 with TDelegationToken

use of org.apache.accumulo.core.security.thrift.TDelegationToken in project accumulo by apache.

the class MasterClientServiceHandler method getDelegationToken.

@Override

    if (!master.security.canObtainDelegationToken(credentials)) {
        throw new ThriftSecurityException(credentials.getPrincipal(), SecurityErrorCode.PERMISSION_DENIED);
    }
    // Round-about way to verify that SASL is also enabled.
    if (!master.delegationTokensAvailable()) {
        throw new TException("Delegation tokens are not available for use");
    }
    final DelegationTokenConfig config = DelegationTokenConfigSerializer.deserialize(tConfig);
    final AuthenticationTokenSecretManager secretManager = master.getSecretManager();
    try {
        Entry<Token<AuthenticationTokenIdentifier>, AuthenticationTokenIdentifier> pair = secretManager.generateToken(credentials.principal, config);
        return new TDelegationToken(ByteBuffer.wrap(pair.getKey().getPassword()), pair.getValue().getThriftIdentifier());
    } catch (Exception e) {
        throw new TException(e.getMessage());
    }
