Subject [jira] [Created] (HDFS-5400) DFS_CLIENT_MMAP_CACHE_THREAD_RUNS_PER_TIMEOUT constant is set to the wrong value
Date Tue, 22 Oct 2013 00:03:42 GMT
Colin Patrick McCabe created HDFS-5400:
------------------------------------------

             Summary: DFS_CLIENT_MMAP_CACHE_THREAD_RUNS_PER_TIMEOUT constant is set to the
wrong value
                 Key: HDFS-5400
                 URL: https://issues.apache.org/jira/browse/HDFS-5400
             Project: Hadoop HDFS
          Issue Type: Bug
    Affects Versions: 2.2.1
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
         Attachments: HDFS-5400.001.patch

{{DFS_CLIENT_MMAP_CACHE_THREAD_RUNS_PER_TIMEOUT}} is set to the wrong value.  It should be
set to {{dfs.client.mmap.cache.thread.runs.per.timeout}}, but instead it is set to {{dfs.client.mmap.cache.timeout.ms}}.
 The result is that mmap segments cached in the {{ClientMmapManager}} will take much longer
to timeout than they should.
