Created on Mon May 14 17:52:02 2018

Find urls in given releaser page, and write first batch data into es.
Everytime this program runs, two things will happen:
1 All video urls in given releaser page will be fetched and put into redis url pool,
2 All data related to 1 will be fetched and stored into es.

Data in es will be update when run this program once.
