Impala Catalog Server HW Requirement(CPU)

[#1]

Please tell me the requirements of Impala.

In the HW requirements of Catalog Server and Impalad, the CPUs are listed as well, are they correct?
Does Catalog Server also require CPU, Min: 4 - Recommended: 16?

I referred to the following page.

Why do you think catalog server does not need CPU? Catalog daemon needs to load lots of metadata information and it needs power to do so and it could be very intensive depends on how much metadata you have from Hive.

thank you for your answer.

I understood that the Catalog Server requires a CPU as well as Impalad.
