> Key: HADOOP-14138
> URL: https://issues.apache.org/jira/browse/HADOOP-14138
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 2.9.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Critical
> Fix For: 2.8.0, 2.7.4, 3.0.0-alpha3
>
> Attachments: HADOOP-14138.001.patch, HADOOP-14138-branch-2-001.patch
>
>
> As discussed in HADOOP-14132, the shaded AWS library is killing performance
> starting all hadoop operations, due to classloading on FS service discovery.
> This is despite the fact that there is an entry for fs.s3a.impl in
> core-default.xml, *we don't need service discovery here*
> Proposed:
> # cut the entry from
> {{/hadoop-aws/src/main/resources/META-INF/services/org.apache.hadoop.fs.FileSystem}}
> # when HADOOP-14132 is in, move to that, including declaring an XML file
> exclusively for s3a entries
> I want this one in first as its a major performance regression, and one we
> coula actually backport to 2.7.x, just to improve load time slightly there too
