log4jとslf4jの両方が依存関係に入ってたようで
いったんmahoutのほうからlog4jを外した



org.apache.mahout
mahout-math
${apache.mahout.version}


commons-logging
commons-logging



外したらまだある様子なので、
以下のようなエラーがでた・

さらにpomにexclusionを追加して起動しました。
commons-loggingではなく slf4jを使っているため


org.apache.mahout
mahout-math
${apache.mahout.version}


commons-logging
commons-logging


org.slf4j
slf4j-jcl




org.apache.mahout
mahout-utils
${apache.mahout.version}


commons-logging
commons-logging


org.slf4j
slf4j-jcl
