Question

我对cassandra很新，并且使用1.2.10。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。由于我们知道我们不能在cassandra之间使用，我使用大于（＆lt;）和小于（＆gt;）来获取日期范围。这完全似乎适用于cassandra的cqlsh。但是通过pig_cassandra集成，这里是加载函数。

cql://<keyspace>/<columnfamily>?where_clause=time1%3E1357054841000590+and+time1%3C1357121822000430"

这是它抛出的错误。

我们似乎通过修改cassandra源，编译然后在lib文件夹中添加获得的jar文件来解决问题。

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