[jira] [Resolved] (CASSANDRA-4780) Not informative error reporting when calling getNaturalEndpoints for a CF without key_validation_class

["Brandon Williams (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-4780?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brandon Williams resolved CASSANDRA-4780.
-----------------------------------------

    Resolution: Not A Problem

The RMI error isn't really something we can fix, and the second (actual) error should have been the clue that you needed to convert your key to hex, since by default it would be BytesType.  You'd get the same error trying to insert/get in any thrift client that didn't handle the marshaling for you.

> While trying to call getNaturalEndpoints(String,String,String) via jmx(jconsole), got the following:
> {code}Problem invoking getNaturalEndpoints: java.rmi.UnmarshalException: Error unmarshaling return; 
> nested exception is: java.lang.ClassNotFoundException: org.apache.cassandra.db.marshal.MarshalException (no security manager: RMI class loader disabled){code}
> Googling suggested to try out different classpath mysteries[1]
> Doing that from the nodetool was a bit more informative though:
> {code}Exception in thread "main" org.apache.cassandra.db.marshal.MarshalException: cannot parse '28589689-0bf0-9ebf-e405-d8f1d798cd7d' as hex bytes
