Does not start HUE_SERVER

Question

I'm using CDH-6.2.0. and hue.

HUE_LOAD_BALANCER is run fine.

But HUE_SERVER does not run on each node(2 node).

I've looked at the logs, but I can't find any problems. The strange thing is that even if you run the server once, it looks like it is running 4 times in the runcpserver.log as shown in the figure below, and in the supervisor log, you can see a log saying that it was executed too many times.

That's my own log file.

supervisord.log

runcpserver.log

[30/Mar/2021 16:37:11 ] settings INFO Welcome to Hue 4.3.0

[30/Mar/2021 16:37:44 ] settings INFO Welcome to Hue 4.3.0

When i started in Cloudera Manager. CM print that "Supervisor returned FATAL. Please check the role log file, stderr, or stdout."

Thanks.

Hey, @meenzoon Hope this message finds you.

I did get a chance to review your logs:

1. Was there a recent upgrade from CDH5 to CDH6?

2. Are there any other roles in this instance not working?

2021-03-30 16:37:45,512 INFO exited: 178-hue-HUE_SERVER (exit status 0; not expected) 2021-03-30 16:37:46,174 INFO gave up: 178-hue-HUE_SERVER entered FATAL state, too many start retries too quickly

The above indicates there seems to be an issue with Supervisord. However,

3. What do you observe in the Hue role's stderr and stdout?

Hint: You can get the Hue Process's stderr and stdout under

CM > Hue > Instances > Hue Server > Log Files > Stdout and Stderr(Quick-link)

Let us know how it goes.
