Depositing data into Redis

Implementation ideas:
1. Get a list of URL statistics URLs from the Redis cache
2, one by one piece of SQL statistical statement, temporarily cannot support batch calculation, because by a single URL statistics.
3. Send to hive JDBC to execute SQL and wait for the results to be returned
4, each receiving SQL query results, dynamically added to the list collection.
5. Traverse the list collection data, convert it to a JSON object, and push it into the Redis cache.
6, over.
