Subject [jira] [Created] (HDFS-2744) Extend FSDataInputStream to allow fadvise
Date Tue, 03 Jan 2012 20:52:42 GMT
Extend FSDataInputStream to allow fadvise
-----------------------------------------

                 Key: HDFS-2744
                 URL: https://issues.apache.org/jira/browse/HDFS-2744
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: hdfs client
            Reporter: dhruba borthakur
            Assignee: dhruba borthakur


Now that we have direct reads from local HDFS block files (HDFS-2246), it might make sense
to make FSDataInputStream support fadvise calls. I have an application (HBase) that would
like to tell the OS that it should not buffer data in the OS buffer cache.
