Obviously would be nice if the code writing this special format were in the same place as this code reading it. Assumes format like: JOBINSTANCEDATA (jobinstanceid name, ...) 1197,"partitionMetrics","NOTSET" 1198,":1197:step1:0","NOTSET" 1199,":1197:step1:1","NOTSET" 1200,":1197:step2:0","NOTSET"

Parameters:

rootJobExecutionId - JobExecution id of the top-level job

stepName - Step name of the top-level stepName
