9:30 AM - 10:10 AM
Grand Ballroom 220B

China Mobile Limited is the leading telecommunications services provider in China, with more than 800 million active users. In China Mobile, distributed big data clusters are built by branch companies in each province for their unique requirements. Meanwhile, we have built a centralized Hadoop cluster with scale more than 1600 nodes, on which we collect data from dozens of distributed clusters and make analysis for our business.

In this session, we will introduce the architecture of the centralized Hadoop cluster and experience of constructing and tuning this large scale Hadoop cluster. Key points are as follows:
1. About Ambari: we improve Ambari with features like supporting HDFS Federation and Ambari HA , improving its performance and enabling it to support up to 1600 nodes.
2. About HDFS: we build a large HDFS cluster with data up to 60PB, using federation, ViewFS, FairCallQueue. Our best practice of cluster operation and management will also be included.
3. About Flume: We use the reformed Flume to collect data as much as 200TB per day.
