Interconnection Process

Interconnection Process

This section describes the FusionInsight Hadoop interconnection process.

After the OceanStor 9000 and FusionInsight Hadoop are installed and the front-end service network of the OceanStor 9000 can communicate with all Hadoop nodes and client networks, follow the steps in Table 14-8 to complete the interconnection.

When being asked whether to start the Hadoop cluster after FusionInsight Hadoop is successfully installed, you are advised not to enable it. Alternatively, you can disable it before the interconnection starts by choosing Services > More Actions > Stop cluster on the FusionInsight Hadoop Manager.
