Nifi Node status is down

New Contributor

Hi there, 

In Cloudera manager, after installing the parcels of CDH, and CFM.

added the Nifi service by installing nifi csd files in csd repo.

and zookeeper is also added as dependency.

 

After starting the NIFI service, NIFI node status is Down all the time.

And couldn't find any folders like log, conf in the parcel-repo to check the error logs.

 

Nifi node status is unknown health. couldn't start the service. We have hosted the services on a single host.

Please, suggest a way to identify the issue.

 

Below is the directory structure of CFM parcel and nifi files.

I would first check if there is a difference in reporting by CM about service by checking the process status by running  #ps -eaf | grep nifi on host where nifi is service installed and started by CM.

nifi logs logged under default directory /var/log/nifi/  

There you should find bootstrap.log , nifi-app.log and nifi-user.log , if service is started by CM then we should see logging at bootstrap.log and later in nifi-app.log.

if there is any issue while starting the service then you should able to see stdout and stderr logs in CM for nfi start up events as well, let me know if you are to more details, and you can open a support case with Cloudera technical support if you have an active subscription.

 

Thank You.
