[Build MQTT + SQLite + Hadoop Sales Data Pipeline (Proof of Concept, 5 Days) -- 2](https://freelancer.com/projects/40766222.html) PROJECT OVERVIEW We need a small, working proof of concept that collects retail sales transactions over MQTT, stores them locally in SQLite, loads them into Hadoop (HDFS + Hive) and produces basic sales reports. Everything must run on one machine with Docker so we can demo it and build on it later. DATA FLOW 1. A sales simulator (Python) publishes transactions to an MQTT broker (Mosquitto) 2. A collector subscribes and saves every message in SQLite (it keeps working if Hadoop is down) 3. A loader moves new SQLite rows to HDFS on a schedule and on demand 4. Hive tables on HDFS and SQL queries produce the sales reports DELIVERABLES 1. docker-compose.yml: Mosq...
