Authentication Issue: X509CertificateExtractor No client certificate found in request.

Hello all,

I am running into an issue with authentication when trying to connect my Flink (version 1.14.3) server with NiFi. NiFi 1.15.3 is running in secure mode in cluster with 3 nodes. When my Flink flow try to connect to NiFi, it throws:

 

Flink Log:

I'm using same certificates in all NiFi nodes and Flink node. The certs are all in place and I confirmed there is one PrivateKeyEntry with ExtendedKeyUsages set to serverAuth and clientAuth. I searched for solution and I could not able to find one in the forum.

Note: The IP: 16.13.8.6 in the log is my Flink node

Please let me know what I'm missing.

Appreciate any help on this!

Thanks,
Prabu.

@spserd ,

 

Are the NiFi 1.11 and 1.15 clusters different clusters or the same cluster that you upgraded?

Is the application using the same keystore to connect to both clusters?

Would you be able to share the part of your application code where you construct your NiFiSource?

 

Cheers,

André

Ah! Thanks a lot for taking the time to post the solution, @spserd !

 

I suspect that there was one detail that wasn't mentioned: did you also upgrade Java from 8 to 11 between the two clusters?

 

In Java 8 the default keystore/truststore type used to be JKS and in Java 11 the default changed to PKCS12. If the store type isn't set explicitly, this error would certainly happen when upgrading Java.

 

Cheers,

André

Hello @araujo - Yes. That is the issue. From Java 11, we may need to explicitly set the keystore type.

 

Thanks,
