Description
The Hadoop Distributed Filesystem (HDFS) requires one unique server, the namenode, which manages the block locations of files on the filesystem. The jobtracker is a central service which is responsible for managing the tasktracker services running on all nodes in a Hadoop Cluster. The jobtracker allocates work to the tasktracker nearest to the data with an available work slot.
