Typed from my new ubuntu set up on an old piece of hardware.
Trying to follow instructions from Hadoop Beginner’s Guide book.
Install Ubuntu from a USB stick
Complication: UEFI and Secure Boot – (It seems that I have to disable Secure Boot)
Things to do after installing Ubuntu [link1] [link2]
Install JDK from Oracle Linux ARM version is for non-intel CPU
Use tar to unpack gz; use sudo to gain permission to /usr/local/
Download Hadoop src
Setup ssh key. sshd is the server side daemon required to ssh to. Need to install sshd before you can ssh to the server (local).
Hadoop configuration dir moved (since 2.0?), many online tutorials as well as the my book tells me to go to $HADOOP_HOME/conf, which is confusing.
Getting errors trying to start hdfs. Need to figure out which user hadoop runs with.
