    cat <<EOF
Script to query Cloudera Navigator API, auto-populating Cloudera Navigator host address, cluster name from environment and
safely passing credentials via a file descriptor to avoid exposing them in the process list as arguments or OS logging
history

Arguments are passed through to curl (eg. -k to not verify internal self-signed SSL certificate)

Combine with jq commands to extract the info you want

Environment variables (prompts for address and password if not passed via environment variables):

\$CLOUDERA_NAVIGATOR_HOST / \$CLOUDERA_NAVIGATOR
\$CLOUDERA_NAVIGATOR_SSL (any value enables SSL and changes default port from 7186 to 7187)
\$CLOUDERA_NAVIGATOR_USER / \$CLOUDERA_USER / \$USER
\$CLOUDERA_NAVIGATOR_PASSWORD / \$CLOUDERA_PASSWORD / \$USER

    ./cloudera_navigator_api.sh /path

Used by various adjacent cloudera_navigator_*.sh scripts

Tested on Cloudera Enterprise 5.10
