Subject [jira] [Commented] (CASSANDRA-4814) Always gossip DC and Rack information
Date Wed, 17 Oct 2012 06:34:04 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13477663#comment-13477663

Sylvain Lebresne commented on CASSANDRA-4814:
---------------------------------------------

The new generic code in StorageService to push the dc/rack with gossip calls the snitch getDatacenter()
and getRack() methods with the broadcast address. But for GPFS those methods used to always
check gossip even for the local host, which won't work if those are used to set the info for
the local host.

> Currently, we only gossip the DC and rack of nodes if a snitch that needs that information
is used. However, in the spirit of CASSANDRA-4351, it would be useful to always gossip that
information as an easy way for client libraries to access it (so that they can more easily
implement strategy like "connect only to node local to my DC").
