Why does ignite-rest-http disable my logging?

Question

I have ignite-core working nicely with my application's log by including the ignite-slf4j module and calling config.setGridLogger(new Slf4jLogger). However, when I include the ignite-rest-http module, all of my log output disappears. How do I get it back, and include any logging from ignite-rest-http?

Answer 1

It happens because ignite-rest-http module has slf4j-log4j12 as a dependency for some reason.

To make logging over slf4j work with Rest API enabled I had to exclude slf4j-log4j12 and log4j dependencies from classpath.

For example, in Maven it is achieved by editing the dependency entry:

<dependency>
    <groupId>org.apache.ignite</groupId>
    <artifactId>ignite-rest-http</artifactId>
    <version>2.3.0</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-log4j12</artifactId>
        </exclusion>
        <exclusion>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>
