Antonio Murgia created HADOOP-18993:
---------------------------------------
Summary: Allow to not isolate S3AFileSystem classloader when needed
Key: HADOOP-18993
URL: https://issues.apache.org/jira/browse/HADOOP-18993
Project: Hadoop Common
Issue Type: Improvement
Components: hadoop-thirdparty
Affects Versions: 3.3.6
Reporter: Antonio Murgia
Fix For: 3.4.0
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.
I propose to add a configuration key {{fs.s3a.extensions.isolated.classloader}}
with a default value of {{true}} that if set to {{false}} will not perform the
classloader set.
