------------------------------------------------
Summary: Add logic for verifying that the STS URL is in the
correct format
Key: HADOOP-19103
URL: https://issues.apache.org/jira/browse/HADOOP-19103
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Reporter: Narayanan Venkateswaran
* At present an invalid URL can be supplied as an STS endpoint. It will attempt
to create an STSClient with it and then fail with,
{quote}java.net.UnknownHostException: request session credentials:
software.amazon.awssdk.core.exception.SdkClientException: Received an
UnknownHostException when attempting to interact with a service. See cause for
the exact endpoint that is failing to resolve. If this is happening on an
endpoint that previously worked, there may be a network connectivity issue or
your DNS cache could be storing endpoints for too long.:

{quote} * This is inefficient. An invalid URL can be parsed much earlier and
can be failed based on the URL format itself.
* The error message is not very clear and does not indicate a problem in the
URL format.
* In this Jira issue, we attempt to parse the STS URL and fail fast with a
more relevant error message.
