Hbase and zookeeper Data Structure Query

I. Preface

Over the past year, I have been busy with business analysis and top-level design for specific projects, and have little time and effort to focus on specific technical details. In addition to the improvement of architecture concepts and analysis capabilities, at the specific technical level, there has not been much progress. For some reason, I was always asked about some technical details, and many details were blurred. Take some time to review them. The Technology Section will be the focus of the next phase.

Ii. operation instructions

There are two main channels to view hbase data in zookeeper: 1. view the data through the hbase shell command zk_dump; 2. view the data through zk_cli.sh;

V. Description

I will not elaborate on the output results. If you are interested, ask du Niang.
