Invalid method name: 'query'

用Impala连接查询报错
`
$impala = new \ThriftSQL\Impala('....**, 21055, '1234');

$impalaTables = $impala->connect()->query('show tables');

print_f($impalaTables);
`
报错信息：
Thrift \ Exception \ TApplicationException (1) Invalid method name: 'query'

I look forward to your help！
