Subject [jira] Commented: (CASSANDRA-1047) Get hadoop ColumnFamily metadata from describe_keyspace instead of config file
Date Fri, 11 Jun 2010 16:10:14 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1047?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12877842#action_12877842

Jeremy Hanna commented on CASSANDRA-1047:
-----------------------------------------

I wonder if there could be some way to just have the subset of configuration information that
it needs in a cassandra.yaml file.  I can look into that - that way, they're not overspecifying
having to come up with all that info that they don't really need, and it's still in a configuration
file so code wouldn't be required for the case of pig.

> Requiring the Hadoop job to contain a copy of the Cassandra configuration file is clunky
and error-prone.  Instead, the Hadoop job should get an IP and port to contact for the range
map and for CF metadata (with describe_keyspace).
