Analysis of the timeout problem of ZooKeeper cluster
The three nodes of the ZK installed by CDH are basically the default configuration. They have been used normally. Today there is a problem.
The client connection timeout is 6 times longer, and the

Hadoop cluster time synchronization
1. Cluster time synchronization
Find a machine, as a practical server, all machines will synchronize with the cluster time regularly, for example, synchronize the time every ten minutes.
1.1 Steps
Do you use AKKA Cluster to run separate Actor systems on each host in a distributed system?
This is my assumption based on Stackoverflow reading.
You have multiple system components:
>Database
>Authentication
>Network
As described in the microservice model, each system

HeartBeat V2 CRM implements NFS-based mysql high availability cluster
Foreword
Because the built-in resource manager haresource function of heartbeat v1 is relatively simple and does not support graphical management, Therefore, heartbeat v2 no longer supports h
