I have Hadoop 1.0.4 running on a single node cluster set up on my Ubuntu machine.
I did the following steps to download and install the hive release
Just find your hive-exec-*.jar folder and create a symbolic link to it.
in my case, first i go to hive folder using "cd /usr/local/Cellar/hive/1.2.1"
and then run command "ln -s libexec/lib/ lib"
