Good afternoon. when starting apache nifi 2.0.0 M2 (as well as M1, M3, M4), after a while it closes with an error, the java_home variable is defined, nifi_properties indicated its IP. please tell me what the problem is and a possible solution

@livsey Welcome to the Cloudera Community!

To help you get the best possible solution, I have tagged our NiFi experts @SAMSAL @cotopaul @ckumar  who may be able to assist you further.

Please keep us updated on your post, and we hope you find a satisfactory solution to your query.

[#3]

Did u find any solution for this.Currently I am facing this type of issue

[#4]

@livsey 

Can you share what Java and Java version you are using and how you have configured your Apache NiFi conf/nifi.properties file?

I am most interested in the Web Properties section.

Thank you,
Matt

@MattWho 

Hi Matt, I am having the same issue as:

Here are my web properties:

and java version as below:

Please suggest any resolution. 

[#6]

@Kiranq  @livsey 

If you configure "nifi.web.https.host" with your actual Windows hostname or IP rather then using the loopback address (127.0.0.1), does your NiFi start?

Any custom add-ons?

Have you set NiFi to debug in logback to see if any additional logging shed some light here?

Thanks,
Matt

[#7]

The NiFi actually starts for the first time, if I close it and try to restart it, it never gets restarted again. 

No custom add ons.

I dont know how to debug in logback.

The only error from today seem to be repeating:

I am also having these erros, if it helps you in any way.

This error shared:

2024-10-17 08:35:19,764 ERROR [Timer-Driven Process Thread-5] o.a.n.c.s.StandardControllerServiceNode StandardControllerServiceNode[service=CSVRecordLookupService[id=a8b84b00-b0ee-31c8-dbda-7e7e9795ba4b], name=CSVRecordLookupService, active=true] Encountering difficulty enabling. (Validation State is INVALID: ['CSV File' is invalid because CSV File is required, 'Lookup Key Column' is invalid because Lookup Key Column is required]). Will continue trying to enable.

Indicates that NiFi is trying to enable a NiFi Controller services loaded from the flow.json.gz during startup, but cannot because it's configuration is invalid.  It is complaining about the configuration of the "CSV File" and "Lookup Key Column" properties.

Have you tried starting your NiFi with the following setting in your nifi.properties file set to "false":

nifi.flowcontroller.autoResumeState=false

This will start NiFi and all components on the canvas will not be started during startup.
Also if you NiFi is at the point it is trying to enable components on the canvas, Your NiFi is up and running.

As far as the screenshot error, have you verified ownership and permissions on that directory path.  Permissions can be an issue if you started the NiFI service as different users at some point in time resulting in some files created on startup having different ownership.
