Subject [jira] Updated: (CASSANDRA-1420) Using config-converter, some fields are not converted
Date Mon, 23 Aug 2010 16:22:25 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-1420?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jon Hermes updated CASSANDRA-1420:
----------------------------------

    Attachment: 1420.txt

FramedTransport was a simple fix: if it's false, set to zero and WARN, else (true or null)
set to the default (15mb frame size).

EndPointSnitch is not as nice.  In 0.6, there was a snitch-per-keyspace instead of a global
snitch. 
If not all EPS values match, a ConfigurationException is thrown.
If all match o.a.c.l.EndPointSnitch, it converts to o.a.c.l.RackInferringSnitch and WARNs
instead.
If all match some other value, it leaves the class name as-is, and gives them an INFO.

> When running the config-converter, the value of EndPointSnitch isn't transfered to the
yaml version.
> The dynamic_snitch value is added, though.
> I imagine the value of org.apache.cassandra.locator.EndPointSnitch should be converted
to org.apache.cassandra.locator.RackInferringSnitch rather than to SimpleSnitch.
> Also, <ThriftFramedTransport>false</ThriftFramedTransport> is not converted
to the yaml version.
> That is, the configuration uses the new default for 0.7 which is framed transport.
> Perhaps, for the benefit of the users, the config-converter should produce informative
messages on both issues after the operation is complete to make the user aware that the defaults
have changed, so that the user will look into it.
