Minifi is failing with following error:

I have placed the aws nifi nars:

nifi-aws-nar-1.5.0.3.1.2.0-7.nar
nifi-aws-service-api-nar-1.5.0.3.1.2.0-7.nar

in my minifi lib directory

/home/centos/minifi-0.4.0.3.1.2.0-7/lib

I have verify the permission on the jar are fine. Any ideas?

As a result of the the HDF build versioning and how the NiFi extension manager handles versions there is, unfortunately, one additional NAR that is needed. You should also provide the nifi-standard-services-api-nar-1.5.0.3.1.2.0-7.nar that coincides with nifi-aws-service-api-nar-1.5.0.3.1.2.0-7.nar. Without this, I would imagine that in your log you will see warnings that it could not find the needed standard services api NAR. This additional requirement is a biproduct of the HDF specific builds.
