URL: https://github.com/apache/hadoop/pull/7942
### Description of PR
S3A fails to initialize when S3 bucket namespace is having dot followed by a
number.
Specific Problem: URI parsing fails when S3 bucket names contain a dot
followed by a number (like bucket-v1.1-us-east-1). Java's
URI.getHost() method incorrectly interprets the dot-number pattern as a port
specification, causing it to return null.
### How was this patch tested?
Tested in us-east-1 with bucket having namespace with dot followed by a
number.
### For code changes:
- [x] Does the title or this PR starts with the corresponding JIRA issue id

- [x] Object storage: have the integration tests been executed and the
endpoint declared according to the connector-specific documentation?
- [ ] If adding new dependencies to the code, are these dependencies
