The operators in the submitted application were fused by using the default legacy fusion scheme because the application was not compiled on Version 4.2, or later.

The Streams Application Manager ignored the instance.fusionScheme or submitjob setting. The operators were fused the same way that they were fused before Version 4.2.
To use the new Version 4.2 fusion schemes, recompile the application on Version 4.2, or later. Then, submit the job again.
