> fs.s3a.classloader.isolation=false configuration does not work - classloader
> not retrieved from Configuration object
> --------------------------------------------------------------------------------------------------------------------
>
> Key: HADOOP-19833
> URL: https://issues.apache.org/jira/browse/HADOOP-19833
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.4.0, 3.5.0, 3.4.1, 3.4.2, 3.4.3, 3.4.4, 3.5.1
> Reporter: Yunzhao Yang
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0, 3.5.0, 3.4.1, 3.4.2, 3.4.3, 3.4.4, 3.5.1
>
>
> The configuration {{fs.s3a.classloader.isolation=false (introduced from
> https://issues.apache.org/jira/browse/HADOOP-18993)}} does not work as
> intended. While the configuration is correctly set in the Hadoop
> Configuration object, the S3A classloader is never retrieved from the Hadoop
> Configuration object, resulting in classloader isolation always being enabled
> regardless of the {{fs.s3a.classloader.isolation}} value.
>
> The bug occurs in two steps:
> *Configuration is set correctly* - The isolation flag is properly stored in
> the Hadoop Configuration object. Code link:
> [https://github.com/apache/hadoop/blob/release-3.5.0-RC0/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AUtils.java#L1756]
>
> *Classloader is not retrieved from Configuration* - When creating instances,
> the classloader is not read from the Configuration object, instead it is
> always using the S3AUtils's classloader. Code link:
> [https://github.com/apache/hadoop/blob/release-3.5.0-RC0/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AUtils.java#L660]
