Raw reflection not used to accelerate select star query

Hi Darian, do you have any additional logging about the substitution error in server.log? If not, you can try enabling this to see if you get the actual error:

<appender name="acceleration" class="ch.qos.logback.core.rolling.RollingFileAppender">
  <file>${dremio.log.path}/acceleration.log</file>
  <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <fileNamePattern>${dremio.log.path}/archive/acceleration.%d{yyyy-MM-dd}.log.gz</fileNamePattern>
    <maxHistory>30</maxHistory>
  </rollingPolicy>
  <encoder>
    <pattern>%date{ISO8601} [%thread] %-5level %logger{36} - %msg%n</pattern>
  </encoder>
</appender>

<logger name="com.dremio.exec.planner.acceleration" additivity="false">
    <level value="debug" />
    <appender-ref ref="acceleration" />
</logger>
<logger name="com.dremio.reflection.bup" additivity="false">
  <level value="debug" />
  <appender-ref ref="acceleration" />
</logger>
<logger name="com.dremio.reflection.ReflectionTracer" additivity="false">
  <level value="debug" />
  <appender-ref ref="acceleration" />
</logger>

The log message will contain the job id in the thread name to help you find the relevant messages.
