Использую hadoop-2.6.0 и mahout-distribution-0.9 и пытаюсь запустить всё это под cygwin на win7 x64.
Cygwin terminal:
cd C:/Users/user/Downloads/Hadoop/mahout-distribution-0.9
export JAVA_HOME="C:/Program Files/Java/jdk1.8.0_31"
export HADOOP_HOME="C:/Users/user/Downloads/Hadoop/hadoop-2.6.0"
examples/bin/classify-20newsgroups.sh
Получаю ошибку:
