apache-zookeeper - Storm升级-zookeeper的问题

Question

从storm 0.9.1升级到0.9.2后，我在尝试运行nimbus时遇到以下异常:

杀死 QuorumPeerMain 后，nimbus 就能够运行了。 看起来 Zookeeper 有问题，或者旧 zk 版本的一些痕迹仍然缓存在某处。

什么可能导致此问题？

Answer 1

终于找到原因了。

快速解决方案:从 Zookeeper 中递归删除 Storm 节点并重新运行。

zookeeper Storm节点中的旧数据与新安装的storm冲突，导致serialVersionUID不匹配。
