     [ https://issues.apache.org/jira/browse/HADOOP-3146?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Runping Qi updated HADOOP-3146:
-------------------------------

    Description: 
Starting fron hadoop-0.17, calling flush of dfs becomes very expensive.
The current implementation of flush should be renamed as sync.


  was:
Starting fron hadoop-0.17, calling flush of dfs becomes very expensive.
It does not make much sense to call flush inside append.


        Summary: DFS flush should be light weighted  (was: SequenceFile should not call flush excessively)
