CDF - Add NiFi CA Service Service to Cluster - FileNotFoundException

Sheldon_G — Sat, 08 Jun 2019 15:44:25 GMT

Using CM with CDF, using Parcels, trying to Add NiFi CA Service to cluster. Got the following error while trying to activate roles:

In looking around the fs, I see that the missing files are in fact under a different path, starting at /var/run/cloudera-scm-agent/process/.

The files are in /var/run/cloudera-scm-agent/process/89-nifitoolkitca-NIFI_TOOLKIT_SERVER.

Does anyone know why the parcel installer would put files in a location that is slightly different, but still in the .../process/... path?

@anung @Sheldon_G @Nando ,

I'm sorry to hear you are hitting this issue. Let me walk through the install and see if I can lend a hand. What instructions are you using?

I tested on CM 6.2 and did not encounter the problem on CFM 1.0.1.0.

My process directory (created by CM/agent for the process to start) does not include the file.

However, the config.zip that is in the process directory does contain it:

[root@host-10-17-100-225 2537-nifitoolkitca-NIFI_TOOLKIT_SERVER]# unzip -l config.zip

I saw one hint in an internal discussion that permissions on /var/lib/nifi* could be an issue... can you do an "ls -lrt /var/lib/nifi*" and show the results?

I'll work with the NiFi team on Monday to see if we can get this working for you.

Hi Bgooley,

thank you for responding, I tried sith Support Portal but CDF is not there yet 😛

I dont have /var/lib/nifi in the server. strange...

should I mkdir manually?

I'm using instruction from Hortonworks sites

Re: CDF - Add NiFi CA Service Service to Cluster - FileNotFoundException

bgooley — Mon, 15 Jul 2019 02:16:42 GMT

@anung,

I also used the instructions here: https://docs.hortonworks.com/HDPDocuments/CFM/CFM-1.0.1/installation/content/overview.html

I tested by making sure that the CA service could not access /var/lib/nifitoolkit and reproduced the error you are seeing.

I did the following:

chown root:root nifitoolkit/

chmod 700 nifitoolkit/

drwx------ 3 root root 4096 Jul 13 13:44 nifitoolkit

I get:

Caused by: java.io.FileNotFoundException: /var/run/cloudera-scm-agent/process/2549-nifitoolkitca-NIFI_TOOLKIT_SERVER/staging/globals.xml (No such file or directory)
	at java.io.FileInputStream.open0(Native Method)
	at java.io.FileInputStream.open(FileInputStream.java:195)

So, yes, the process must be able to create the /var/lib/nifitoolkit directory and it must be owned by "nifitoolkit".

You can try:

mkdir /var/lib/nifitoolkit

chown -R nifitoolkit:nifitoolkit /var/lib/toolkit

Then try restarting. If there is still a problem, let's look at your ls -lart /var/lib output

@bgooley Yes this fixed it for me. It was a permissions issue.
