"volumes": [
{
"containerPath": "/${KRB5CCNAME}",
"hostPath": "/${KRB5CCNAME}",
"mode": "RO"
}
]
So the nice thing about our patch was that substitutions were done earlier.
its wrong because we probably leak memory as we didn't want to change the
mutability of taskInfo. Your patch is much smaller, but then the subsequent
logic examines the arguments prior to expansion and goofs up the paths at least.

> a Marathon app, hence] the Task's CommandInfo, so that the executor is able
> to detect the correct values at runtime.
