Example 3

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

• 16 cores
• 128 GB memory
• 12 drives

This cluster is similar to Example 1, but less memory-constrained. It is important to be conservative with the number of map and reduce slots to avoid flooding the cluster with random disk I/O:

• 24 map slots
• 9 reduce slots
• Give the leftover 41 GB to MapR-FS
