You needn't specify the log4j configuration file, the one in hbase-server/src/test/resources will get put in the test classpath for you.
The default appender in that file is on stderr, which surefire will swallow somewhere in the temp directory it creates for running things. Usually when I need log output from tests, I activate the daily rolling file appender from the command line. ex: mvn -Dtest=TestTableSnapshotInputFormat#testInitTableSnapshotMapperJobConfig -Dhbase.root.logger=DEBUG,DRFA package this will place the log output in hbase-server/hbase.log On Fri, Nov 14, 2014 at 3:15 PM, Stephen Boesch <[email protected]> wrote: > I still have not been able to locate the testing logs output.
