------------------------------
Summary: Add configuration to control blocks deletion asynchronous
or synchronous
Key: HDFS-16524
URL: https://issues.apache.org/jira/browse/HDFS-16524
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode
Reporter: leo sun
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.
