>         Attachments: sample_request.txt
> We were upgrading from Flink 1.4 to 1.6. At present we have a jar which takes all the
details to run the job as program args against a jarid, including sql query and kafka details.
In version 1.5 the program args are tokenised as a result single quote (') and double quote(")
are stripped from the arguments. This results in malformed args.
> Attached a sample request for reference.
