Subject [jira] [Commented] (HDFS-2885) Remove "federation" from the nameservice config options
Date Wed, 09 May 2012 06:06:22 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2885?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13271131#comment-13271131

Eli Collins commented on HDFS-2885:

The only difference is that "dfs.federation.nameservices" would become "dfs.nameservices"
and  "dfs.federation.nameservice.id" (which is typically not set) would become "dfs.nameservice.id".
Same before/after for both HA and federation configs except the word "federation" is not used.

> HDFS-1623, and potentially other HDFS features will use the nameservice abstraction,
even if federation is not enabled (eg you need to configure {{dfs.federation.nameservices}}
in HA even if you're not using federation just to declare your nameservice). This is confusing
to users. We should consider deprecating and removing "federation" from the {{dfs.federation.nameservices}}
and {{dfs.federation.nameservice.id}} config options, as {{dfs.nameservices}} and {{dfs.nameservice.id}}
are more intuitive.
