Syed Shameerur Rahman updated HADOOP-19681:
-------------------------------------------
Description:
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.
{{}}
{code:java}
hadoop dfs -ls s3a://bucket-v1.1-us-east-1/
WARNING: Use of this script to execute dfs is deprecated.
WARNING: Attempting to execute replacement "hdfs dfs" instead.
2025-09-08 06:13:06,670 WARN fs.FileSystem: Failed to initialize filesystem
s3://bucket-v1.1-us-east-1/: java.lang.IllegalArgumentException: bucket is
null/empty
-ls: bucket is null/empty{code}
{*}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.
