Subject [jira] Updated: (HADOOP-3146) SequenceFile should not call flush excessively
Date Tue, 01 Apr 2008 04:26:24 GMT

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

Owen O'Malley updated HADOOP-3146:
----------------------------------

    Component/s:     (was: mapred)
                 dfs
    Description: 
Starting fron hadoop-0.17, calling flush of dfs becomes very expensive.
It does not make much sense to call flush inside append.


  was:

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



Actually, I would vote for HDFS to make flush cheaper again. Flush should *not* mean that
your bytes have reached the disk. It should only mean that they have been sent to the operating
system.
