Description

Hi everyone,

 

I have deployed a storm 2.4.0 cluster on my dev machine. However, when I look up the worker's log, I found that every half minute, there is a continuously zookeeper shutdown phenomenon. 

 

While I have listened the zookeeper port, the connection number is remain the same in a long period of time, which represents that the connection between storm nimbus and zookeeper is stable.

 

The log record is attached as below, may I know why this zookeeper shut down phenomenon happens? And is it means something failed or it is a normal thing?

 

Thx!
