Chesnay Schepler created FLINK-34499:
----------------------------------------
Summary: Configuration#toString should hide sensitive values
Key: FLINK-34499
URL: https://issues.apache.org/jira/browse/FLINK-34499
Project: Flink
Issue Type: Improvement
Components: Runtime / Configuration
Reporter: Chesnay Schepler
Fix For: 1.20.0
Time and time again people log the entire Flink configuration for no reason,
risking that sensitive values are logged in plain text.
We should make this harder by changing {{Configuration#toString}} to
automatically hide sensitive values, for example like this:
{code}
@Override
public String toString() {
return ConfigurationUtils
.hideSensitiveValues(this.confData.entrySet().stream().collect(
Collectors.toMap(Map.Entry::getKey, entry ->
entry.getValue().toString())))
.toString();
}
{code}
