mapreduce job does not have tracking url

[#1]

I am learning hadoop using hortonworks with HADOOP 3.

in localhost 8188, all the MapReduce Appllication tracking url are unassigned. when I click into the application_id of a MapReduce job, it shows Failed to read the attempts of the application application_1593635743443_0027. What is the problem with it?

Besides, in AMBARI, TEZ,PIG, and SQOOP services show neither "started" nor "stopped", but only "1 installed" under the summary section. Is that normal? In shell, I can run SQOOP job normally.

Thanks!

Hey, could you share the exact trace of output that you receive? If the issue is on the WebUI, could you also share the Screenshot of what you see?
