Example 2

In this example 10-node cluster, each node has the following characteristics:

• 16 cores
• 32 GB memory
• 4 drives

This hardware has a small number of drives; with limited disk I/O capacity, run a conservative number of map and reduce slots:

• Not more than 2 or 3 reduce slots
• Not more than 8 map slots
• Give the leftover 6G memory to MapR-FS
