ABSTRACT:
Embodiments of the invention provide techniques for determining the correctness of similar job plan segments in a stream processing application. In one embodiment, a job manager may be configured to identify similar job plan segments based on data formats, functionality, and surrounding processing elements. The job manager plan may be further configured to determine whether the similar segments provide inconsistent results, and if so, to determine which of the inconsistent similar segments is invalid. The job manager may identify an invalid processing element included in the invalid segment. The job manager may also perform corrective actions to address the invalid processing element.
