[jira] Created: (HDFS-896) Support flush in HDFS

Support flush in HDFS
---------------------

                 Key: HDFS-896
                 URL: https://issues.apache.org/jira/browse/HDFS-896
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: hdfs client
    Affects Versions: 0.22.0
            Reporter: Hairong Kuang
            Assignee: Hairong Kuang
             Fix For: 0.22.0


HADOOP=6313 describes three flush APIs. This jira aims to support API1 in HDFS:

API1: flushes out from the address space of client into the socket to the data nodes. On the return of the call there is no guarantee that that data is out of the underlying node and no guarantee of having reached a DN. New readers will eventually see this data if there are no failures.
