pentaho-version: 8.3.0.0-371
There is a probability of a null pointer problem during the parallel execution of jobs with Kettle, leading to process exit. This problem occurs when kettle executes the job in parallel, but there is no problem when executing the job serially.
Job description：Multiple work nodes are parallelized after a conversion node. There is no dependency between each work node, but the variables in the conversion node will be obtained. Multiple work nodes are executed to the success node and end. The process can be viewed by clicking "Click to view kettle job"
