------------------------------------
Summary: Internal cpu configuration option is leaked in logs
Key: FLINK-20503
URL: https://issues.apache.org/jira/browse/FLINK-20503
Project: Flink
Issue Type: Bug
Components: Runtime / Configuration
Affects Versions: 1.11.2, 1.12.0
Reporter: Xintong Song
The configuration option `taskmanager.cpu.cores` is meant for internal usages
only and should not be advertised to users atm.
However, the following logs could be printed when Flink runs in local
environment, which not only leaks the option to the users, but may also mislead
them to explicitly set it.
{quote}"The configuration option taskmanager.cpu.cores required for local
execution is not set, setting it to xxx".
{quote}
The log comes from `TaskExecutorResourceUtils#adjustForLocalExecution`.
