[jira] [Commented] (HADOOP-17437) Update Hadoop Documentation with a new AWS Credential Provider used with EKS

    [ https://issues.apache.org/jira/browse/HADOOP-17437?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17250897#comment-17250897 ]

----------------------------------------

I'm opening this issues to request to update Hadoop Documentation for S3 Authentication with a new Credential Provider that is used by EKS (Amazon Elastic Kubernetes Service) to authenticate to AWS Services. 

Document to update - https://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/index.html#Authenticating_with_S3

I tried setting up Hive Metastore service on EKS and while using S3 I got access denied issues wherein my K8s pod already assumed the correct Service Account which has access to S3. After some troubleshooting, I figured out we need to add following property in core-site.xml for Hive to Authenticate to S3 while running on EKS - 

<property>
    <name>fs.s3a.aws.credentials.provider</name>
    <value>com.amazonaws.auth.WebIdentityTokenCredentialsProvider</value>
  </property>

This property is currently not mentioned in the documentation yet. I tested this using - 

Hadoop 3.2.0
aws-java-sdk-bundle-1.11.874.jar
hadoop-aws-3.2.0.jar
