com.cloudera.cdp.authentication.credentials.CdpCredentialsProviderChain
All Implemented Interfaces:
CdpCredentialsProvider
Direct Known Subclasses:
DefaultCdpCredentialProviderChain
public class CdpCredentialsProviderChain extends Object implements CdpCredentialsProvider
CdpCredentialsProvider that chains together multiple credentials providers. When a caller first requests credentials from this provider, it calls all the providers in the chain, in the original order specified, until one can provide credentials, and then returns those credentials. If all of the credential providers in the chain have been called, and none of them can provide credentials, then this class will throw an exception indicated that no credentials are available.
