How to track operator behavior via metadata
Embodiments presented herein describe techniques for tracking operators of a distributed computing environment (e.g., a streams processing environment) using metadata. During execution of a distributed application of the computing environment, a tracker tool monitors a plurality of operators of the distributed application. Each of the operators stores one or more specified metadata values associated with the operator. For each operator, the tracker tool retrieves the one or more specified metadata values associated with the operator. Upon determining that one of the one or more specified metadata values do not comply with a corresponding expected metadata value, the tracker tool generates an indicator for the operator. The indicator includes information describing the one or more specified metadata values.
