Hi there! So a little background. I've been trying to setup Hive on a CentOS 6 machine. I followed the instructions of this Youtube video: http://www.youtube.com/watch?v=L2lSrHsRpOI
For my case, I'm using Hadoop-1.1.2 and Hive-0.9.0, all the directories labeled "mnt" in this video I replaced it with "opt" because that's where all of my hadoop and hive packages have been opened up. As I reached the portion of the video where I was actually supposed to run Hive via "./hive" this error popped up: "Cannot find hadoop installation: $HADOOP_HOME must be set or hadoop must be in the path" I guess one of the questions I have is, in which directory did I have to edit the ".profile" file? because I don't understand why we would have to go to the "home" directory for this change. And also if this helps, this is what I had put down in the ".profile" file in my /home/hadoop directory export HADOOP_HOME=/opt/hadoop/hadoop export HIVE_HOME=/opt/hadoop/hive export PATH=$HADOOP_HOME/bin:$HIVE_HOME/bin Thank you so much! Sincerely, Gerald Park
