@Robin Dong in Ambari, go to the host you want sqoop to run from and in the "install clients" drop down, choose install sqoop client. When that completes, go to services page and click refresh clients. Once that completes, you should be able to execute sqoop command.

@Kyle Pifer yes, as a general rule of thumb, check the docs first, then HCC, then wiki :).
