Thanks Abhishek for replying Steps 1- After installed storm .. i downloaded storm-starter to run it on storm 2- running WordCountTopology using maven "build successfully" 3- trying to submit a topology on storm ui . using storm jar 4- i used storm jar SNAPSHOT with dependencies and worked well .. 5- trying to use storm jar user@ubuntu:~/Storm/storm$ bin/storm jar storm-starter.jar storm.starter.WordCountTopology wordcount but it didn't work got this error "cannot find or load main class of WordCountTopology"
but i want to tell you something i guessed that it's the reason when i imported package of storm starter in Eclipse to run code of it .. i found error it's backtype package not defined !!
