At present, we have more than 500 Elasticsearch clusters, with thousands of nodes. The Elasticsearch versions are 6.3.2, 7.2 and 7.4. In order to solve the log4j vulnerability, if you choose to upgrade the Elasticsearch version on a large scale, it will affect the online business. The cost is relatively high. I have recently referred to other repair methods, such as replacing the log4j jar version with 2.17.2. Which method is currently considered? give me some advice
Have a look at this thread.
Thank you, if I can't use the solution of replacing the jar package,
can I refer to this solution ：
It seems like that would apply to your 6.3.2 clusters but not the 7.x ones.
Yes, only handles Elasticsearch version 6.3.2, excluding 7.x
Elasticsearch version 6.3 is EOL and no longer supported. Please upgrade ASAP.
