> S3A: Add option fs.s3a.classloader.isolation (#6301)
> ----------------------------------------------------
>
> Key: HADOOP-18993
> URL: https://issues.apache.org/jira/browse/HADOOP-18993
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/s3
> Affects Versions: 3.3.6
> Reporter: Antonio Murgia
> Assignee: Antonio Murgia
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0, 3.5.0, 3.4.1
>
>
> In HADOOP-17372 the S3AFileSystem forces the configuration classloader to be
> the same as the one that loaded S3AFileSystem. This leads to the
> impossibility in Spark applications to load third party credentials providers
> as user jars.
> The option fs.s3a.classloader.isolation (default: true) can be set to false
> to disable s3a classloader isolation;
> This can assist in using custom credential providers and other extension
> points.
