File bin/bootstrap_system.sh:

> But I don't want it to check out to ~/Impala. I explicitly set IMPALA_HOME
In summary, with my change, the script will respect IMPALA_HOME it's set. If 
not, the default IMPALA_HOME will be ~/Impala. For example, if we download the 
bootstrap_system.sh script from GitHub.

/home/foo/tmp/Impala does not exist
IMPALA_HOME=/home/foo/tmp/Impala ./bootstrap_system.sh (will clone Impala in 
/home/foo/tmp/Impala and run a build in /home/foo/tmp/Impala)

~/Impala does not exist
./bootstrap_system (will clone Impala in the default IMPALA_HOME, which is 
~/Impala and run the build in ~/Impala)

/home/foo/tmp/Impala already exists
IMPALA_HOME=/home/foo/tmp/Impala ./bootstrap_system.sh (will skip the clone, 
but will run the build in /home/foo/tmp/Impala)

~/Impala exists
./bootstrap_system.sh (will skip the clone, but will run the build in the 
default IMPALA_HOME, which is ~/Impala)
