Subject [jira] [Commented] (HADOOP-15387) Produce a shaded hadoop-cloud-storage JAR for applications to use
Date Mon, 04 Feb 2019 18:19:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15387?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16760085#comment-16760085
] 

Steve Loughran commented on HADOOP-15387:
-----------------------------------------

well hadoop-client-api could perhaps be used, but it'd mean that that jar explicitly included
things which are @Private types for internal use by various hadoop cloud modules. Doable?

>                 URL: https://issues.apache.org/jira/browse/HADOOP-15387
>             Project: Hadoop Common
>          Issue Type: New Feature
>          Components: fs/adl, fs/azure, fs/oss, fs/s3, fs/swift
>    Affects Versions: 3.1.0
>            Reporter: Steve Loughran
>            Priority: Major
>
> Produce a maven-shaded hadoop-cloudstorage JAR for dowstream use so that
>  * Hadoop dependency choices don't control their decisions
>  * Little/No risk of their JAR changes breaking Hadoop bits they depend on
> This JAR would pull in the shaded hadoop-client JAR, and the aws-sdk-bundle JAR, neither
of which would be unshaded (so yes, upgrading aws-sdks would be a bit risky, but double shading
a pre-shaded 30MB JAR is excessive on multiple levels.
> Metrics of success: Spark, Tez, Flink etc can pick up and use, and all are happy
