I duplicated the issue in the 2.0 release on a Windows 10 machine.
> parallelJobsNumber does not prevent concurrent execution
> --------------------------------------------------------

> Key: IGNITE-5183
> URL: https://issues.apache.org/jira/browse/IGNITE-5183
> Project: Ignite
> Issue Type: Bug
> Components: compute
> Affects Versions: 1.5.0.final, 1.9, 2.0
> Environment: Windows7, WIndows 8, Windows 10
> Reporter: Ryan Ripken
> Attachments: IgniteTest.7z
>
>
> Using FifoQueueCollisionSpi with parallelJobsNumber == 1 does not prevent
> multiple jobs from executing at the same time.
> Emails sent to Users list April 10th, 11th, 12th.
> Attached example which reproduces issue in Ignite 1.5.
> One node needs to run node.bat
> Another node should execute IgniteTest class.
> This example looks for concurrent execution using a static AtomicInteger,
> when multiple executions are detected it prints a message with lots of
> asterisks.
> The example also exhibits the issue in Ignite 1.9
> Example output:
