Ali Data Platform Division massive data technology expert Rolly: Building a cross-room Hadoop cluster

PPT Download--The seventh session of the BDTC 2013

Rolly introduces the status of the ladder of the Alibaba Hadoop cluster, and the background of the deployment across the engine room. Ali set up the Hadoop cluster from 2008, and was launched in 2009. After that, the cluster code has been maintained by the company itself. As the scale increases, you will need to face the problems of Hadoop deployment and scalability across the engine room. He said storage utilization of more than 80% is a very dangerous signal, especially with some machine data very full, and even two thousand or three thousand units reaching 98%, which is very dangerous. Calculation utilization of nearly 100%, to achieve the deployment of a cross room, the difficulty is actually very much, including not support namenode expansion, how to solve the bandwidth, how to distribute the data, and finally how to transfer this room 90% data, the data volume reached more than 50 p, migration will be very slow.
