Commit Message:

Line 17: To build the ASF tree, set $DOWNLOAD_CDH_COMPONENTS to true.
> Can you point to the ASF repo: https://git-wip-us.apache.org/repos/asf?p=in
Done


Line 20: Once the integration jenkins job is modified to periodically
> Can you elaborate here - which job, specifically?
Details of the jenkins job is added. The followings are replies to other 
questions. They are details of our internal process so I won't add that to the 
commit message.

The existing integration jenkins job will periodically download the latest CDH 
components and run Impala tests along with these new components. If all tests 
pass, they will be checked into the thirdparty directory and overwrite the 
previous version checked in. For the new procedure, the jenkins job will do the 
same testing as before. The only difference is that it will upload the latest 
stable version of CDH components to the S3 bucket. The details of which has to 
be worked out as it involves some atomic renaming.

If a user wants to run their own version of CDH components (e.g. ASF version of 
Hadoop), that's perfectly fine but they may need to update impala-config.sh 
with the appropriate version string of Hadoop he/she is using. There is no 
guarantee it will pass all the Impala tests with such configuration as we don't 
plan to test (and officially support) such configuration.
