Hi everyone, I am facing an issue while running a Sqoop import job. The process gets stuck at: INFO mapreduce.Job: map 0% reduce 0% The job does not progress further. Additionally, I see the following message in the logs: INFO conf.Configuration: resource-types.xml not found. INFO resource.ResourceUtils: Unable to find 'resource-types.xml'. Despite this, there are plenty of available resources in the cluster, so resource allocation should not be the problem. I also have 3 healthy nodes. I’ve tried various troubleshooting steps, but I haven’t been able to resolve the issue. Could the "resource-types.xml not found" warning be causing this problem? If so, where should the resource-types.xml file be placed in a Cloudera Data Platform (CDP) setup? Any help or suggestions would be greatly appreciated! ... View more

I have a NiFi cluster consisting of 3 nodes, and I secured the cluster using a single signed certificate for all nodes. However, I am encountering an error that I suspect might be due to using just one certificate.
