             Summary: Change ConstraintSolverStrategy::backtrackSearch to avoid 
StackOverflowException
                 Key: STORM-3519
                 URL: https://issues.apache.org/jira/browse/STORM-3519
             Project: Apache Storm
          Issue Type: Bug
          Components: storm-server
    Affects Versions: 2.0.0
            Reporter: Bipin


When ConstraintSolverStrategy::backtrackSearch recursively call itself - after 
approximately 20000 calls, there is a StackOverflowException. This can be 
replicated by running 
TestConstraintSolverStrategy::testScheduleLargeExecutorConstraintCount.
