Cassandra - 关于新ColumnFamily创建的NullPointerException

我遇到了这里描述的确切问题https://issues.apache.org/jira/browse/CASSANDRA-4363但是使用了Cassandra 1.1.2，cqlsh --cql3 .

当我尝试创建列族时，我得到的错误是

Traceback (most recent call last):
  File "./cqlsh", line 1008, in perform_statement
    self.cursor.execute(statement, decoder=decoder)
  File "./../lib/cql-internal-only-1.0.10.zip/cql-1.0.10/cql/cursor.py", line 117, in execute

    plus = self.handle.send(buff)
error: [Errno 32] Broken pipe

有时我只是让TSocket读取0个字节 .

服务器端日志也与JIRA票证中提到的相同 .

我尝试删除/ var / lib / cassandra目录并重新启动服务器 . 我仍然得到错误 . JIRA中的此错误已标记为“无法重现”，“固定版本无” . 那么我该如何让我的cassandra再次工作呢？
