Hi,
We faced a problem of loading logging class when start the name node. It
seems that hadoop can not find commons-logging-*.jar
We have tried other commons-logging-1.0.4.jar and
commons-logging-api-1.0.4.jar. It does not work!
The following are error logs from starting console:
I'd drop the -api file as it isn't needed, and as you say, avoid
duplicate versions. Make sure that log4j is at the same point in the
class hierarchy too (e.g in hadoop/lib)
to debug commons logging, tell it to log to stderr. It's useful in
emergencies
-Dorg.apache.commons.logging.diagnostics.dest=STDERR
