----------------------------------------------
Summary: Fix S3A failing to initialize S3 buckets having namespace
with dot followed by number
Key: HADOOP-19681
URL: https://issues.apache.org/jira/browse/HADOOP-19681
Project: Hadoop Common
Issue Type: Bug
Components: fs/s3
Reporter: Syed Shameerur Rahman
Assignee: Syed Shameerur Rahman
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.

Please Note: Although there has been discussion on not allowing S3 buckets with
such a namespace
(https://aws.amazon.com/blogs/aws/amazon-s3-path-deprecation-plan-the-rest-of-the-story/)
, Amazon S3 still allows you to create a bucket with such a namespace.{{{}{}}}
