Description

BIGTOP-2989 and BIGTOP-2992 introduced support for LOCAL_DOWNLOADS_DIR environment variable as a location to check before downloading from Internet. This improvement aims to formalize this variable for the following:

• For Hadoop, always download the file to this directory so that it can be reused in the build via a file:// URL
• For Pig, use this directory even if a download is necessary.
• Add details on this variable to confluence.
