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.
