Utf 8 Cassandra 1.2.5-无效的UTF8字节

我正在向CF读写大量数据

过了一会儿，我发现以下错误：

注意，我最近从cassandra 1.1.4升级到cassandra 1.2.5（我不知道它是否相关） java版本：1.6.0_32

有人知道如何解决这个问题吗

原因：org.apache.cassandra.db.marshall.marshallException:无效的UTF8字节374638333943C080746656C65666F6E6F73206170617261746F7320792061636365736F72696F73

你在这个中间有无效的UTF-8字节。

具体而言，从第17个字节开始的2字节序列

c080

无效。不确定要使用哪个字符，可能是

NUL

字符（在UTF-8中应该是

00

）。UTF-8中的第一个2字节序列是

c280

，对应于Unicode

U+0080

损坏的UTF-8编码器？
