Troubleshooting access to S3 buckets from a Yandex Data Processing 1.4 cluster

Issue descriptionIssue description

When attempting to access S3 buckets from a Yandex Data Processing 1.4 cluster, you see this error:

ls: doesBucketExist on yc-mdb-examples: com.amazonaws.AmazonClientException: 
No AWS Credentials provided by ComputeMetadataCredentialsProvider : com.amazonaws.AmazonServiceException: Bad Request (Service: null; Status Code: 400; Error Code: null; Request ID: null)

Meanwhile, the cluster hosts have network access to S3.

SolutionSolution

Create a new cluster with Yandex Data Processing version 2.0 or higher: the specified error does not occur there, and the connection to the bucket is valid.
