NIFI-14161: Fix QueryCassandra Processor Attribute Loss Issue

[Rahul937303]

Resolved an issue in the QueryCassandra processor where attributes from the incoming FlowFile were occasionally lost in subsequent FlowFiles when the processor split the results due to a configured Fetch Size (e.g., 750). This fix ensures that all FlowFiles maintain the original attributes, even when multiple FlowFiles are generated from a single query result.

Thanks for pull request! Any commit that should land on NiFi 1.x should be via a PR against the branch https://github.com/apache/nifi/tree/support/nifi-1.x. However, I don't think the community is willing to invest additional time in making new releases for the 1.x branch. It is, of course, up to any committer/PMC member to decide if such a release should happen though and if, collectively, enough people are willing to go through the release process which is quite time consuming.

As per the end of support notice on https://nifi.apache.org/download/ I dont think this change should proceed.

Please submit this change against the 2.x branch if appropriate. Thanks

Hi joewitt
Currently, there is no 2.x branch available. Could you please clarify where this change should be submitted?
