RE: Nifi 1.14.0 not launching after copying nifi-splunk-nar-1.15.3.nar

["Chirthani, Deepak Reddy" <C-...@charter.com>]

Hey Matt,

So we were able to delete GetSplunk 1.14.0 nar file and were able to launch Nifi 1.14.0 with GetSplunk 1.15.3 nar uploaded in the lib folder successfully. Even though this is not ideal way but it was working in nifi 1.14.0 as required.

However, when we did the same for the Nifi version 1.12.1, even though successfully launched after restart, GetSplunk 1.15.3 is throwing out an error and we are unable to retrieve anything. Below is the error,

GetSplunk[id=xxxx-xxxx-xxxx-xxxx] GetSplunk[id=xxxx-xxxx-xxxx-xxxx] failed to process session due to org.apache.nifi.processor.ProcessSession.getState(Lorg/apache/nifi/components/state/Scope;)Lorg/apache/nifi/components/state/StateMap;; Processor Administratively Yielded for 1 sec: java.lang.NoSuchMethodError: org.apache.nifi.processor.ProcessSession.getState(Lorg/apache/nifi/components/state/Scope;)Lorg/apache/nifi/components/state/StateMap;

Obviously, as you mentioned GetSplunk 1.15.3 is not compatible with Nifi version 1.12.1. What we need is an enhancement to GetSplunk 1.12.1 with the following properties:

1) Connection Timeout
2) Read Timeout

We are currently running our Nifi version 1.12.1 and facing hung threads issue<https://issues.apache.org/jira/browse/NIFI-9093?page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel&focusedCommentId=17438829#comment-17438829> and we are not ready for 1.15.3 nifi upgrade. It would be great if we can get backporting of the patch on 1.12.1 GetSplunk processor.

Subject: Nifi 1.14.0 not launching after copying nifi-splunk-nar-1.15.3.nar

Hello,

We are currently using GetSplunk processor to pull data from Splunk Enterprise on a scheduled basis in our Nifi – 1.12.1 instance. We have observed that new properties added to the GetSplunk processor in the latest version of Nifi 1.15.3 and we would like to bring that processor to our current instance of Nifi to meet our requirements.

For accomplishing this, we brought the nifi-splunk-nar-1.15.3.nar file and tested that by uploaded it to the lib folder of a separate Nifi-1.14.0(local instance) and restarted it. Nifi – 1.14.0 was unable to launch however it was able to launch if I removed that particular nar file.

Any suggestions why this is happening? In the past we were able to bring processors from lower versions of Nifi successfully but not higher versions.

Thanks
