Docker broker Log4j config references a missing query log appender

[dlscjf151]

Problem

docker/images/pinot/etc/conf/pinot-broker-log4j2.xml defines the rolling-file appender as querylog, but org.apache.pinot.broker.querylog.QueryLogger references queryLog.

<RollingFile name="querylog" ... />
...
<AppenderRef ref="queryLog"/>

Appender names are case-sensitive. Because the query logger also has additivity="false", broker query records are not written to querylog.log and do not fall back to the root appenders.

The non-Docker broker config already references querylog correctly.

Proposed fix

Change the Docker config reference to:

<AppenderRef ref="querylog"/>

Validation

• Parsed the XML successfully.
• Verified every AppenderRef resolves to a declared appender after the change.
• Ran root-scoped Spotless, license, and Checkstyle validation.
