[jira] [Created] (HDFS-16524) Add configuration to control blocks deletion asynchronous or synchronous

leo sun created HDFS-16524:
------------------------------

             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.
