Impala - Kerberos: GSS Initiate Failed occurring after previously successful attempts

This issue has been reported numerous times but mine comes with a particular wrinkle. The first few connection attempts authenticate and write to Impala successfully. It's only on the final two calls that I receive the following:


2018-01-19 14:47:28,469 ERROR [main] org.apache.thrift.transport.TSaslTransport: SASL negotiation failure GSS initiate failed [Caused by GSSException: No valid credentials provided (Mechanism level: Failed to find any Kerberos tgt)]


My connection string is as follows:




And I build my connection like so:


static {
    try {

    } catch (ClassNotFoundException e) {        LOG.error(e.toString());

Connection getConnectionFromDriverManager() throws SQLException{
    return DriverManager.getConnection(connectionUrl);

public void InsertImpala(Collection<Entries> Entries) {

    Connection conn;

    try {        conn = getConnectionFromDriverManager();

        } catch (SQLException e) {



Can anyone offer any direction?
