Step 11: Inspect Cluster

The Inspect Cluster page provides a tool for inspecting network performance as well as the Host Inspector to search for common configuration problems. Cloudera recommends that you run the inspectors sequentially.

Minimum Required Role: Limited Cluster Administrator (also provided by Full Administrator and Cluster Administrator)

1. Run the Inspect Network Performance tool. You can click Advanced Options to customize some ping parameters.
2. After the network inspector completes, click Show Inspector Results to view the results in a new tab.
3. Address any reported issues, and click Run Again (if applicable).
4. Click Inspect Hosts to run the Host Inspector utility.
5. After the host inspector completes, click Show Inspector Results to view the results in a new tab.
6. Address any reported issues, and click Run Again (if applicable).
7. If the reported issues cannot be resolved in a timely manner, and you want to abandon the cluster creation wizard to address them, select the radio button labeled Quit the wizard and Cloudera Manager will delete the temporarily created cluster and then click Continue. Otherwise, after addressing any identified problems, select the radio button labeled I understand the risks, let me continue with cluster creation, and then click Continue.

This completes the Add Cluster - Installation wizard and launches the Add Cluster - Configuration wizard. For further instructions, see Set up a Cluster Using the Wizard in the Installation guide.
