--------------------------------------
Summary: ElasticSearchClientServiceImpl malformed (nonstandard?)
expires attribute when connecting through AWS LoadBalancer
Key: NIFI-11766
URL: https://issues.apache.org/jira/browse/NIFI-11766
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.19.1
Environment: Ubuntu 22.04, EC2 machine in AWS,
Java: 11.0.18, AWS
Reporter: Marek Radwański
Each request to elasticsearch from a processor that utilizes
ElasticSearchClientServiceImpl to connect to the cluster results in a logged
Warning entry of:
2023-06-30 11:11:42,194 WARN [I/O dispatcher 2]
o.a.h.c.protocol.ResponseProcessCookies Invalid cookie header: "Set-Cookie:

Expires=Fri, 07 Jul 2023 11:11:42 GMT; Path=/; SameSite=None". Invalid
'expires' attribute: Fri, 07 Jul 2023 11:11:42 GMT
Resulting in millions of those entries accumulating over time on a large
cluster.
This seems like a mismatch of cookie standards the underlying HTTP client uses
and what AWS ALB expects.
