Cassandra - 创建新ColumnFamily时发生NullPointerException

Question

我遇到了如https://issues.apache.org/jira/browse/CASSANDRA-4363所述的确切问题，但使用了Cassandra 1.1.2，cqlsh --cql3。

当我尝试创建一个列族，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 
    response = self.handle_cql_execution_errors(doquery, prepared_q, compress) 
    File "./../lib/cql-internal-only-1.0.10.zip/cql-1.0.10/cql/cursor.py", line 132, in handle_cql_execution_errors 
    return executor(*args, **kwargs) 
    File "./../lib/cql-internal-only-1.0.10.zip/cql-1.0.10/cql/cassandra/Cassandra.py", line 1583, in execute_cql_query 
    self.send_execute_cql_query(query, compression) 
    File "./../lib/cql-internal-only-1.0.10.zip/cql-1.0.10/cql/cassandra/Cassandra.py", line 1593, in send_execute_cql_query 
    self._oprot.trans.flush() 
    File "./../lib/thrift-python-internal-only-0.7.0.zip/thrift/transport/TTransport.py", line 293, in flush 
    self.__trans.write(buf) 
    File "./../lib/thrift-python-internal-only-0.7.0.zip/thrift/transport/TSocket.py", line 117, in write 
    plus = self.handle.send(buff) 
error: [Errno 32] Broken pipe 

，有时我只是得到TSocket阅读0字节。

服务器端日志也与JIRA票证中提到的相同。

我试着删除/ var/lib/cassandra目录并重新启动服务器。我仍然得到错误。 JIRA中的此错误已被标记为无法重现，固定版本无。 那么我该怎么做才能让我的卡桑德拉再次工作？

Answer 1

https://issues.apache.org/jira/browse/CASSANDRA-4526表明这被固定在1.1.3中。我会升级（到1.1.4，最新版本）。
