This article will explain in detail how to solve the clock deviation of CDH cluster machines. The content of the article is of high quality. Therefore, Xiaobian shares it with you as a reference. I hope you have a certain understanding of relevant knowledge after reading this article.

1. Phenomenon:

The home interface and host interface diagrams and component status identifiers are gray (normal is green)
