> Key: PARQUET-1723
> URL: https://issues.apache.org/jira/browse/PARQUET-1723
> Project: Parquet
> Issue Type: Improvement
> Reporter: David Mollitor
> Assignee: David Mollitor
> Priority: Minor
> Labels: pull-request-available
>
> I see a few places with the following pattern...
>
> {code:java}
> if (map.contains(key)) {
> return map.get(key);
> }
> {code}
> Better to just call {{get()}} and then check the return value for 'null' to
> determine if the key is there. This prevents the need to traverse the
> {{Map}} twice,... once for {{contains}} and once for {{get}}.
