The problem is with the toConsole(). I've removed it and now I get only one
output (I'm logging at debug level). I've modified my logback.xml so the
console definition is in the file.
<configuration>
<appender name="Console" class="ch.qos.logback.core.ConsoleAppender">
<!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
<encoder>
<pattern>====> %msg%n</pattern>
</encoder>
</appender>
<root>
<level value="error" />
<appender-ref ref="Console"/>
</root>
</configuration>
Removed the .toConsole(),
LogFixtureBuilder logBuilder = LogFixture.builder()
// Log to the console for debugging convenience
.logger("org.apache.drill.exec.store.msgpack", Level.DEBUG);
try (LogFixture logs = logBuilder.build()) {
Also another issue I was having is that I was getting 3 outputs initially.
I was picking up this logback file because logback tries to load
logback-test.xml before logback.xml.
https://github.com/apache/drill/blob/7b0c9034753a8c5035fd1c0f1f84a37b376e6748/common/src/test/resources/logback-test.xml
Should I be using a logback-text.xml in my personal project or should that
common logback-test.xml be removed ?
Thanks Paul
