Depends what the log4j.properties file that your code is picking up says. mvn test or IDE "run" test classes should pick up src/test/resources/log4j.properties, which will log to stderr. If that's how you're running you could tweak the hadoop logging level to see if it shows anything more. Change:
log4j.logger.org.apache.hadoop=WARN to INFO or DEBUG. Also, mvn test will redirect the log output to target/surefire-reports/org.apache.hadoop.hbase....-output.txt On Tue, Apr 12, 2011 at 12:43 PM, Jason Rutherglen < [email protected]> wrote: > Where does MiniDFSCluster store the logs?
