Viraj Jasani commented on HADOOP-18980:
---------------------------------------
{quote}exactly; though i'd expect the remapping to be from com.amazonaws to
software.amazonaws or private implementations
key goal: you can use the same credentials.provider list for v1 and v2 sdk
clients.
{quote}
In addition to having same credentials.provider list for v1 and v2 sdk, maybe
we can also remove static mapping for v1 to v2 credential providers and let new
config have default key value pairs:
{code:java}
<property>
<name>fs.s3a.aws.credentials.provider.mapping</name>
<value>
com.amazonaws.auth.AnonymousAWSCredentials=org.apache.hadoop.fs.s3a.AnonymousAWSCredentialsProvider,
com.amazonaws.auth.EC2ContainerCredentialsProviderWrapper=org.apache.hadoop.fs.s3a.auth.IAMInstanceCredentialsProvider,
com.amazonaws.auth.InstanceProfileCredentialsProvider=org.apache.hadoop.fs.s3a.auth.IAMInstanceCredentialsProvider,
com.amazonaws.auth.EnvironmentVariableCredentialsProvider=software.amazon.awssdk.auth.credentials.EnvironmentVariableCredentialsProvider,
com.amazonaws.auth.profile.ProfileCredentialsProvider=software.amazon.awssdk.auth.credentials.ProfileCredentialsProvider
</value>
</property> {code}
With this being default value, any new third-party credential provider can be
added to this list by users. Does that sound good?

> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.4.0
> Reporter: Steve Loughran
> Priority: Minor
>
> s3afs will now remap the common com.amazonaws credential providers to
> equivalents in the v2 sdk or in hadoop-aws
> We could do the same for third party credential providers by taking a
> key=value list in a configuration property and adding to the map.
