我有一个带有cassandra和搜索节点的双数据中心部署。它看起来像这样：
ubuntu@ip-172-31-25-223:~$ dsetool ring
Note: Ownership information does not include topology, please specify a keyspace.
Address DC Rack Workload Status State Load Owns VNodes
172.31.47.194 Solr 2a Unknown Up Normal 3.17 GB 0.00% 1
172.31.39.59 us-west-2 2a Unknown Up Normal 2.32 GB 31.53% 512
172.31.9.36 us-west-2 2c Unknown Up Normal 3.43 GB 33.48% 512
172.31.25.223 us-west-2 2b Unknown Up Normal 3.25 GB 34.99% 512
Warning: Node 172.31.25.223 is serving 1.11 times the token space of node 172.31.39.59, which means it will be using 1.11 times more disk space and network bandwidth. If this is unintentional, check out http://wiki.apache.org/cassandra/Operations#Ring_management
我最近添加了172.31.39.59节点，我想在其他节点上运行清理以删除一些重复数据。
在nodetool cleanup节点上运行172.31.25.223会产生以下跟踪：
ubuntu@ip-172-31-25-223:~$ nodetool cleanup

我是Datastax企业的新手，我对Cassandra-＆gt; Solr以及管道工作方式的了解不多。我很感激任何帮助！
谢谢！

更新：尝试再次运行它并且这次得到了不同的跟踪：
ubuntu@ip-172-31-25-223:~$ nodetool cleanup

答案 0 :(得分：1)
清理错误的修复程序在我们最新发布的4.5.3版本中，即2014年11月4日的GA。
滚动升级应该是直接的/没有停机时间。
这是发行说明：

修复了在非Solr工作负载上导致空指针异常的问题 节点持有Solr数据并尝试运行nodetool清理 对数据的命令。 （DSP-4310）
