Invalid method name: 'query'

[chenfeizhou]

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！
