Closed via #220

[peterzhuamazon]

The rootcause is still unclear but the reason of error has been found.
See log: dataprepper-2.0.2-install.txt

When install without any security settings, aws-sdk-s3 as a transient dependency to aws-sdk is being installed as 1.134.0.
https://github.com/opensearch-project/logstash-output-opensearch/blob/main/logstash-output-opensearch.gemspec#L48

When switching to any of the security settings, it will then fall back to 1.131.0, as shown in the log above.

Since aws-sdk-s3 never being signed, when running with -P HighSecurity, it will fail the run due to high security requires all packages to be signed, no matter having signature or not.

[opensearch@fa202d0638a5 logstash-output-opensearch]$ gem install logstash-output-opensearch-2.0.2-java.gem -P HighSecurity

-r--r--r-- 1 opensearch opensearch   1358 Aug 24 18:10 metadata.gz

The solution is to follow this order:

1. Install without security
2. Uninstall logstash
3. Install with MediumSecurity
4. Uninstall logstash
5. Install with HighSecurity
6. Successfully installed gem

It is possible to directly install with MediumSecurity to start with tho.

Thanks.
