The Analytics Hadoop Cluster consists of the following systems:
- 1 master node (NameNode, ResourceManager, etc.)
- 1 standby NameNode and ResouceManager
- 42 x worker nodes (DataNode, NodeManager).
The hardware infrastructure page has the system description and configurations.
We run Cloudera's CDH5.
See Hue documentation for jobs running on Hadoop and hunting down logs.
See the Administration page for servicing individual nodes or understanding the cluster better.
