CDF - Add NiFi CA Service Service to Cluster - FileNotFoundException

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

@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

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?
