问题
i'm new to storm i submitted different topologies form github like storm-starter and others successfully after some problem i faced it but some of the some spout didn't emit ! like that
is that right ? or is there a problem ?
where can i find the result after submitting topology ?
i guessed in the result file in storm folder but it's empty !
this what i have in the bolt "one of them "
回答1:
There is no explicit "result" file in storm. Your topology is responsible for handling/storing results wherever/whenever you need to. You can check the log files from each worker for logs (System.out calls or logger bindings) or you can have a sink bolt that writes whatever result you need locally to a file on the machine where it is being executed or you can have an hdfsBolt to write the results to an hdfs file or you can have an external server that receives results via sockets from your last bolt, etc...
The list is endless, it is up to you.
