Subject [jira] [Created] (HDFS-2923) Namenode IPC handler count uses the wrong configuration key
Date Thu, 09 Feb 2012 05:15:59 GMT
Namenode IPC handler count uses the wrong configuration key
-----------------------------------------------------------

                 Key: HDFS-2923
                 URL: https://issues.apache.org/jira/browse/HDFS-2923
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 0.23.0, 0.23.1
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical


In HDFS-1763, there was a typo introduced which causes the namenode to use dfs.datanode.handler.count
to set the number of IPC threads instead of the correct dfs.namenode.handler.count. This results
in bad performance under high load, since there are not nearly enough handlers.
