James Wing commented on NIFI-1325:
----------------------------------
I like the update, thank you for making those changes. Since the Default
Credential in AWS can be sufficient to assume a role, I recommend making two
changes to AWSCredentialsProviderControllerService:
1. customValidate: Removing the validation requirement that either API keys or
a file be specified in addition to the role information.
1. onConfigured: Creating the default credential after API keys/file credential
but before assuming a role, then using the credentialsProvider to do so.
I have attached a patch file demonstrating these changes on top of your patch
0005 (JW_Patch_On_MS_0005.zip).
