First you need to get the list of packages and store it in /etc/apt/sources.list.d/
, then update the packages, then you fire the Impala queries.
At the terminal do the following:
cd /etc/apt/sources.list.d/
wget http://archive.cloudera.com/impala/ubuntu/precise/amd64/impala/cloudera.list
sudo apt-get update
sudo apt-get install impala # Binaries for daemons
sudo apt-get install impala-server # Service start/stop script
sudo apt-get install impala-state-store # Service start/stop script
