This problem bothered me for five days, and for several days I fought hard into the night. I don’t want to eat all day long, but I finally solved it. Because there is little information on the Internet, I’d like to record here. If you have any questions about Doris, please exchange them~

The error information is as follows:

Problem solving:

Delete be under/storage/cluster_ ID
Restart be.

Cause of the problem:

Refer to the official document

it may be that the Fe node has been rebuilt many times, resulting in cluster failure_ If the ID recorded in the ID file is incorrect, deleting the file and restarting be will generally solve the problem.

Note: if it is only port: 0, code: 7, please use telnet to check the connectivity of container port.
