> Avoid static initialization of ObjectMappers
> --------------------------------------------
>
> Key: HADOOP-15550
> URL: https://issues.apache.org/jira/browse/HADOOP-15550
> Project: Hadoop Common
> Issue Type: Bug
> Components: performance
> Affects Versions: 3.2.0
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Minor
> Attachments: hadoop-15550.txt
>
>
> Various classes statically initialize an ObjectMapper READER instance. This
> ends up doing a bunch of class-loading of Jackson libraries that can add up
> to a fair amount of CPU, even if the reader ends up not being used. This is
> particularly the case with WebHdfsFileSystem, which is class-loaded by a
> serviceloader even when unused in a particular job. We should lazy-init these
> members instead of doing so as a static class member.
