Hadoop Summit 2012 | HDFS High Availability

Hadoop NameNode architecture, design, setup and the roadmap for HA NameNode.

The HDFS NameNode is a robust and reliable service as seen in practice in production at Yahoo and other customers. However, the NameNode does not have automatic failover support. A hot failover solution called HA NameNode is currently under active development (HDFS-1623). This talk will cover the architecture, design and setup. We will also discuss the future direction for HA NameNode.
