#Download Hadoop from one of these mirrors. Change the version number appropriately:
RUN wget http://apache.mirrors.tds.net/hadoop/common/hadoop-2.7.2/hadoop-2.7.2.tar.gz -P ~/Downloads
#Extract it to /usr/local:
RUN tar zxvf ~/Downloads/hadoop-* -C /usr/local
#Rename the directory to just hadoop:
RUN mv /usr/local/hadoop-* /usr/local/hadoop
