> Avoid the overhead of copy-on-write exception list while loading inodes sub
> sections in parallel
> ------------------------------------------------------------------------------------------------
>
> Key: HDFS-16891
> URL: https://issues.apache.org/jira/browse/HDFS-16891
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Affects Versions: 3.3.4
> Reporter: Viraj Jasani
> Assignee: Viraj Jasani
> Priority: Major
> Labels: pull-request-available
>
> If we enable parallel loading and persisting of inodes from/to fs image, we
> get the benefit of improved performance. However, while loading sub-sections
> INODE_DIR_SUB and INODE_SUB, if we encounter any errors, we use copy-on-write
> list to maintain the list of exceptions. Since our usecase is not to iterate
> over this list while executor threads are adding new elements to the list,
> using copy-on-write is bit of an overhead for this usecase.
> It would be better to synchronize adding new elements to the list rather than
> having the list copy all elements over every time new element is added to the
> list.
