[jira] [Created] (HDFS-2923) Namenode IPC handler count uses the
wrong configuration key
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.
