Ah. Makes better sense to me.
> Fix TaskManager config keys
> ---------------------------
>
> Key: FLINK-8835
> URL: https://issues.apache.org/jira/browse/FLINK-8835
> Project: Flink
> Issue Type: Bug
> Components: TaskManager
> Reporter: Stephan Ewen
> Assignee: mingleizhang
> Priority: Blocker
> Labels: easy-fix
> Fix For: 1.5.0
>
>
> Many new config keys in the TaskManager don't follow the proper naming
> scheme. We need to clear those up before the release. I would also suggest to
> keep the key names short, because that makes it easier for users.
> When doing this cleanup pass over the config keys, I would suggest to also
> make some of the existing keys more hierarchical harmonize them with the
> common scheme in Flink.
> h1. New Keys
> * {{taskmanager.network.credit-based-flow-control.enabled}} to
> {{taskmanager.network.credit-model}}.
> h1. Existing Keys
> * {{taskmanager.debug.memory.startLogThread}} =>
> {{taskmanager.debug.memory.log}}
> * {{taskmanager.debug.memory.logIntervalMs}} =>
> {{taskmanager.debug.memory.log-interval}}
> * {{taskmanager.initial-registration-pause}} =>
> {{taskmanager.registration.initial-backoff}}
> * {{taskmanager.max-registration-pause}} =>
> {{taskmanager.registration.max-backoff}}
> * {{taskmanager.refused-registration-pause}}
> {{taskmanager.registration.refused-backoff}}
> * {{taskmanager.maxRegistrationDuration}} ==> *
> {{taskmanager.registration.timeout}}
