CREATE TABLE data.banks (
    id text,
    codes frozen<map<text, text>>
 PRIMARY KEY (id,codes));

@Frozen("map<text, text>")在代码字段上添加了带有注释的相应模型类

插入正确但是当我打开 cqlsh 并运行时

select * from data.banks我收到以下错误

Traceback (most recent call last):
  File "/usr/bin/cqlsh", line 1078, in perform_simple_statement
    rows = self.session.execute(statement, trace=self.tracing_enabled)
  File "/usr/share/cassandra/lib/cassandra-driver-internal-only-2.6.0c2.post.zip/cassandra-driver-2.6.0c2.post/cassandra/cluster.py", line 1594, in execute
    result = future.result(timeout)
  File "/usr/share/cassandra/lib/cassandra-driver-internal-only-2.6.0c2.post.zip/cassandra-driver-2.6.0c2.post/cassandra/cluster.py", line 3296, in result
    raise self._final_exception
error: unpack requires a string argument of length 4

另一个问题是当我添加一行值（'1'，{'code2':'435sdfd','code1':'2132sd'}）。它显示插入了一行。但是当我用 ('1',{'code2':'435sdfe','code1':'2132sd'}) 添加另一行时。它抛出 TimedOut 异常。

使用 cassandra 2.1.8 、 cassandra-driver-mapping 2.1.8 、 kundera-cassandra-pelops 3.0 版本。
