> ------------------------------------------------------------------------
>
> Key: HDFS-16524
> URL: https://issues.apache.org/jira/browse/HDFS-16524
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: namenode
> Reporter: leo sun
> Priority: Major

> When users delete files frequently, deletion is slower than its enqueues. The
> pending deletions blocks will keep increasing.
> Under this circumstance, deletion synchronous is better.
> So I will add configuration to switch deletion asynchronous or synchronous.
