我正在向/从 CF 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37464646464646464646464638333943c08074656c65666f6e6f73206170617261746f7320792061636365736f726967

中间有无效的 UTF-8 字节。

c080特别是从第 17 个字节开始的 2 字节序列是无效的。不确定要使用什么字符，可能是NUL字符（应该只是00UTF-8 格式）。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？
