Subject Re: Need IgniteConfiguration and XML at the same time? IgniteStormStreamer?

I have many questions

*1)* This issue really annoying me, here is the error:(occurs in storm

now, i have solved but i need proper solution, because i know that when i
convert to jar, it gives me error(always it gives).
Here is the my solution: according to the this line
I have realized that ignite-storm uses storm and log4j as a dependency
Then I excluded these dependency from pom.xml, and it works. 
However, this is really stupid issue, do i have to care all dependency all
the time?

*2)* Link that you provided says that  // if an ignite instance is already
started in same JVM then use it.
can you explain this. Right now i am working on local mode.
I already open one ignite node on the terminal.
then I open one ignite node inside the storm project
Now, I am opening 2 different JVM or one. (Same question for production
mode, think of it terminal and storm project are inside different machines)

*3)* As far as I know, StormStreamer<String, Integer> igniteStormStreamer =
new StormSt.. () this, it creates new ignite node.
For my project, I have one ignite node on a machine,
Then to get cache data from that machine, I will open another ignite node in
storm (actually in spout inside the open method)
Then I process the datas via spouts bolts etc..  
Then I will write the last processed data to new ignite cache (uses
However, because of I have created ignite node once, when I use
stormstreamer, i am getting IgniteAlreadyStarted exceptions
How can i solved that? (Note that: I have to be sure that one ignite node
will be created in the storm)
