Question

我正在从CF中读取和写入大量数据。

过了一会儿，我收到以下错误：

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

有谁知道如何解决这个问题？

引起：org.apache.cassandra.db.marshal.MarshalException：无效的UTF8字节37464646464646464646464638333943c08074656c65666f6e6f73206170617261746f7320792061636365736f72696f73

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。不确定是什么字符，可能是NUL字符（在UTF-8中应该只是00）。 UTF-8中的第一个2字节序列是c280，对应于Unicode U+0080。

UTF-8编码器损坏了吗？
