> I passed a json string like "{User: Billy, {Age: 18}}" to main method args,
> when running spark jobs on yarn. It may exchange by
> ContainerLaunch.expandEnvironment() to "{User: Billy, {Age: 18" ("}}" to "")
> I found the final arg in launch_container.sh of yarn containers, as:
> --arg '{User: Billy, {Age: 18'
> {code:java}
> exec /bin/bash -c
