org.apache.logging.log4j.core.filter.AbstractFilterable

org.apache.logging.log4j.core.appender.AbstractAppender

org.apache.logging.log4j.core.appender.AbstractOutputStreamAppender<org.apache.logging.log4j.core.appender.OutputStreamManager>

org.apache.hadoop.hbase.logging.HBaseTestAppender

All Implemented Interfaces:

org.apache.logging.log4j.core.Appender, org.apache.logging.log4j.core.filter.Filterable, org.apache.logging.log4j.core.impl.LocationAware, org.apache.logging.log4j.core.LifeCycle, org.apache.logging.log4j.core.LifeCycle2

@Plugin(name="HBaseTest",
        category="Core",
        elementType="appender",
        printObject=true)
public final class HBaseTestAppender
extends org.apache.logging.log4j.core.appender.AbstractOutputStreamAppender<org.apache.logging.log4j.core.appender.OutputStreamManager>

Log4j2 appender to be used when running UTs.

The main point here is to limit the total output size to prevent eating all the space of our ci system when something wrong in our code.

See HBASE-26947 for more details.
