Subject [jira] [Commented] (HDFS-1861) Rename dfs.datanode.max.xcievers and bump its default value
Date Wed, 27 Apr 2011 16:14:03 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1861?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13025871#comment-13025871

Aaron T. Myers commented on HDFS-1861:

Apologies for showing up to this JIRA late, but this JIRA seems like a good opportunity to
have added this config to {{hdfs-default.xml}}, with a helpful description. Changing the name
of it is good, but I believe there's still no documentation about it.

> Reasonably sized jobs and HBase easily exhaust the current default for dfs.datanode.max.xcievers.
4096 works better in practice.
> Let's also deprecate it in favor of a more intuitive name, eg dfs.datanode.max.receiver.threads.
