1. A method comprising: running a first instance of a first extract-transform-load (ETL) job on a first system, with the running of the first instance including generation of first job runtime operational metadata; running a second instance of the first ETL job on a second system, with the running of the second instance including generation of second job runtime operational metadata; responsive to the running of the first and second instances of the first ETL job, determining existence of a job runtime issue with the running of the second instance on the second system; responsive to the determination of existence of the job runtime issue of the second instance on the second system; and correcting the runtime issue with respect to the second system based on intelligent analysis of design and runtime operational metadata; wherein the correction of the runtime issue with respect to the second system comprises: parsing a first runtime log generated by running the first instance and a second runtime log generated by running the second instance, determining information about the runtime issue based on the parsing of the first and second runtime logs, and identifying the failure, and finding out a root cause of the failure based upon the information determined about the runtime issue, wherein the root cause of the failure is one of the following: an environment variable failure, or an output folder failure.
