HA for Nimbus is planned, and there has already been some work in that area:
https://issues.apache.org/jira/browse/STORM-166 Nimbus is not a true SPOF in that if it goes down, you’re topologies will continue to function and process data. With Nimbus down what you lose is the ability to submit/manage topologies and reassign tasks. Without STORM-166, you would have to manually intervene if your nimbus host exploded. If it is a big concern you may want a standby machine and something in your ops pocket to quickly change DNS for your nimbus host. - Taylor On Aug 4, 2014, at 10:55 PM, yang hui <[email protected]> wrote: > HI,all: > how can I make the Nimbus highly available ?
