Description
HADOOP-13727 added the SharedInstanceProfileCredentialsProvider, which effectively reduces high number of connections to EC2 Instance Metadata Service caused by InstanceProfileCredentialsProvider. That patch, in order to prevent the throttling problem, defined new class SharedInstanceProfileCredentialsProvider as a subclass of InstanceProfileCredentialsProvider, which enforces creation of only a single instance.
Per HADOOP-13050, we upgraded the AWS Java SDK. Since then, the InstanceProfileCredentialsProvider in SDK code internally enforces a singleton. SharedInstanceProfileCredentialsProvider can be deprecated as of release 2.9.0.
