Apache Storm 翻译简介

The Storm daemons, Nimbus and the Supervisors, are designed tobe stateless and fail-fast. 

So if they die, they will restart like nothinghappened. 

This means you can kill -9 the Storm daemons without affectingthe health of the cluster or your topologies.

storm 有容错机制, 当worker进死亡时,storm会自动启动..如果一个节点死亡了,那么当前worker会在另外一个节点重新启动..

storm的守护进程, nimbus he supervisors都被设计成无状态及快速失败,也就是说当他们死了,

他们会自动重启,就跟什么都没发生一样,这也就意味着,

当你用kill -9 命令强制kill掉storm守护进程,并不影响集群及你的topology(任务)
