Description

When running eg ./sbin/start-dfs.sh from a tarball the scripts complain JAVA_HOME is not set and could not be found even if the env var is set.

hadoop-0.24.0-SNAPSHOT $ echo $JAVA_HOME
/home/eli/toolchain/jdk1.6.0_24-x64
hadoop-0.24.0-SNAPSHOT $ ./sbin/start-dfs.sh 
log4j:ERROR Could not find value for key log4j.appender.NullAppender
log4j:ERROR Could not instantiate appender named "NullAppender".
Starting namenodes on [localhost]
localhost: Error: JAVA_HOME is not set and could not be found.

I have to explicitly set this via hadoop-env.
