> Key: HDDS-11782
> URL: https://issues.apache.org/jira/browse/HDDS-11782
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Ethan Rose
> Assignee: Tejaskriya Madhan
> Priority: Major
>
> *Observed Behavior:*
> Using {{ozone debug ldb}} {{\-\-with\-keys=true}} or no {{\-\-with\-keys}} flag will print the keys, but {{\-\-with\-keys}} will not print the keys, defaulting to the same as {{{}--with-keys=false{}}}.
> *Explanation*
> We use PicoCLI for our CLI and when we define options like {{--with-keys}} there are two options we can set:
> * [defaultValue|https://picocli.info/apidocs/picocli/CommandLine.Option.html#defaultValue--]: What will be used when the {{--with-keys}} flag is not specified at all
> * [fallbackValue|https://picocli.info/apidocs/picocli/CommandLine.Option.html#fallbackValue--]: What will be used when {{--with-keys}} is specified with no argument
> In the [code|https://github.com/apache/ozone/blob/256aad9df2121946c307daceb512588a8319a81a/hadoop-ozone/tools/src/main/java/org/apache/hadoop/ozone/debug/DBScanner.java#L109] we only set the {{defaultValue}} to {{true}} which leaves the {{fallbackValue}} as {{false}} leading to this unexpected behavior. We should check other CLI flags for this behavior and use acceptance tests to verify proper end-to-end interpretation of CLI flags.
