-----------------------------------
Summary: NetworkBinding has a runtime class dependency on a
third-party shaded class
Key: HDFS-15663
URL: https://issues.apache.org/jira/browse/HDFS-15663
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 3.3.0
Reporter: Chris Wensel
The hadoop-aws library has a dependency on 'com.amazonaws':aws-java-sdk-bundle'
which in turn is a fat jar of all AWS SDK libraries and shaded dependencies.
This dependency is 181MB.
Some applications using the S3AFilesystem may be sensitive to having a large
footprint. For example, building an application using Parquet and bundled with
Docker.
Typically, in prior Hadoop versions, the bundle was replaced by the specific
AWS SDK dependencies, dropping the overall footprint.
In 3.3 (and maybe prior versions) this strategy does not work because of the
following exception:
{{java.lang.NoClassDefFoundError:
com/amazonaws/thirdparty/apache/http/conn/socket/ConnectionSocketFactory}}
