> When I run a sql query, I can't open the stage page on the web, and result the historyserver process shut down. 
> After debug the code, I find a stage graph has more than 5000 same childcluster. so when going to make dot file, the process goes down.
> I think the graph cluster shouldn't has the same child cluster, right?
