Mac OS Catalina Public Beta 2 ( HTTP ERROR 404)

[#1]

I have downloaded Nifi on my laptop running Mac OS Catalina Public Beta 2 and not able to access the UI.

It is up and running and able to access all the REST API's shown below ,

http://127.0.0.1:8080/nifi-api/flow/processor-types

http://127.0.0.1:8080/nifi-api/flow/controller-service-types

http://127.0.0.1:8080/nifi-api/flow/reporting-task-types

http://127.0.0.1:8080/nifi-api/controller/config

http://127.0.0.1:8080/nifi-api/resources

http://127.0.0.1:8080/nifi-api/system-diagnostics

However UI is not accessible , getting below error. Note this is very specific to Mac OS Catalina public beta. it is working fine in Mojave . Nothing stands out in any of the logs.

HTTP ERROR 404

Problem accessing /nifi/. Reason:

    Not Found

For testing purpose , i have downloaded Nifi-Registry and it is also having the same issue.

Is it possible that the browser might be redirecting it to somewhere else. (or any Browser caching issue)

Can you please check if using the CURL call are you getting any different response headers? Can you please share the response headers when CURL using "-ivL" flags ?

Example:

# curl -ivL http://kerlatest6.example.com:8080/nifi
# curl -ivL http://kerlatest6.example.com:8080/nifi-api/flow/processor-types

Also can you please share the output of the following command so that we can see if the process ID is same which is using that port 8080 or different?

# netstat -tnlpa | grep 8080
# ps -ef | grep nifi

.

The above question and the entire response thread below was originally posted in the Community Help track. On Sun Jun 30 21:08 UTC 2019, a member of the HCC moderation staff moved it to the Data Ingestion & Streaming track. The Community Help Track is intended for questions about using the HCC site itself, not technical questions about the Nifi Web UI.

@Samar Aarkotti

Can you please check if your "nifi-web-api-xxx.war" and "nifi-web-ui-xxx.war" NARs are deploying fine in Nifi?

Do you see any message in your "nifi-app.log" for those WARs ? Some message like "with context path set to /nifi" (OR) "with context path set to /nifi-api"

Example:

# grep 'nifi-web-ui' /PATH/TO/nifi-1.9.2/logs/nifi-app*

INFO [main] org.apache.nifi.web.server.JettyServer Loading WAR: /NiFi_Demos/nifi-1.9.2/./work/nar/framework/nifi-framework-nar-1.9.2.nar-unpacked/NAR-INF/bundled-dependencies/nifi-web-ui-1.9.2.war with context path set to /nifi

INFO [main] o.e.jetty.server.handler.ContextHandler Started o.e.j.w.WebAppContext@1018f702{nifi,/nifi,file:///NiFi_Demos/nifi-1.9.2/work/jetty/nifi-web-ui-1.9.2.war/webapp/,AVAILABLE}{./work/nar/framework/nifi-framework-nar-1.9.2.nar-unpacked/NAR-INF/bundled-dependencies/nifi-web-ui-1.9.2.war}

.

OR

# grep 'nifi-web-ui' /PATH/TO/nifi-1.9.2/logs/nifi-app*

INFO [main] org.apache.nifi.web.server.JettyServer Loading WAR: /NiFi_Demos/nifi-1.9.2/./work/nar/framework/nifi-framework-nar-1.9.2.nar-unpacked/NAR-INF/bundled-dependencies/nifi-web-api-1.9.2.war with context path set to /nifi-api

INFO [main] o.e.jetty.server.handler.ContextHandler Started o.e.j.w.WebAppContext@1018f702{nifi,/nifi,file:///NiFi_Demos/nifi-1.9.2/work/jetty/nifi-web-ui-1.9.2.war/webapp/,AVAILABLE}{./work/nar/framework/nifi-framework-nar-1.9.2.nar-unpacked/NAR-INF/bundled-dependencies/nifi-web-ui-1.9.2.war}

.
If not then it indicates that your "/nifi" or "/nifi-api" contexts are not registered properly. Hence those contexts are not accessible from UI/Curl.

In that case i will suggest you to please check the following:

1. The Permission on the directory to know if the NiFi user is able to write to that dir?

# ls -lart  nifi-1.9.2/work/nar/framework/nifi-framework-nar-1.9.2.nar-unpacked/NAR-INF/bundled-dependencies/nifi-web-api-1.9.2.war

2. Check & share the complete nifi startup logs so tat we can findout if there are any issues in getting tose context registered properly?
