DataNode Error: NoClassDefFoundError: org/apache/commons/cli/ParseException

Hi,

I updated to 0.21.0 and have the problem with following error message (see
log attached):

I started hadoop/bin/start-dfs.sh before, log is from one of the nodes.

Classpath seems to be ok (see log please). Can somebody help ?

Thank you very much,

Alexander
