Hadoop Cassandra:原因：InvalidRequestException（原因：无效限制）

我对cassandra和使用1.2.10非常陌生。我有一个主键列，它是timestamp数据类型。现在我正在尝试检索日期范围的数据。因为我们知道在cassandra中不能使用between，所以我使用大于（）来获取日期范围。这在卡桑德拉的cqlsh中似乎非常有效。但对于pig_cassandra积分，这里是负载函数

cql://？其中_子句=time1%3E1357054841000590+和+time1%3C1357121822000430”

这是它抛出的错误

非常感谢您的帮助！！！

我们似乎已经通过修改cassandra源代码、编译并将获得的jar文件添加到lib文件夹中解决了这个问题。

我们还没有找到解决方案。有人可以帮忙吗？
