> [FGL] Make rollEdits thread safe
> --------------------------------
>
> Key: HDFS-17487
> URL: https://issues.apache.org/jira/browse/HDFS-17487
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Reporter: ZanderXu
> Assignee: ZanderXu
> Priority: Major
>
> rollEdits is a very common used RPCs. It is not thread-safe, so it still
> needs to hold the global write lock. So it has a big impact on the
> performance.
>
> We need to make it thread-safe to let it hold the global read lock to improve
> the performance.
