Subject [jira] [Created] (HDFS-6046) add dfs.client.mmap.enabled
Date Tue, 04 Mar 2014 00:45:24 GMT
Colin Patrick McCabe created HDFS-6046:
------------------------------------------

             Summary: add dfs.client.mmap.enabled
                 Key: HDFS-6046
                 URL: https://issues.apache.org/jira/browse/HDFS-6046
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: 2.4.0
            Reporter: Colin Patrick McCabe


It would be nice to have a configuration variable, dfs.client.mmap.enabled. which would disable
mmap reads in the client.  This could come in handy for debugging or performance benchmarking.
