Subject [jira] Commented: (CASSANDRA-66) get_column throws exception on missing column
Date Tue, 21 Apr 2009 16:34:47 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-66?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12701193#action_12701193
] 

Jonathan Ellis commented on CASSANDRA-66:
-----------------------------------------

0002
    return empty lists instead of raising an error where applicable; otherwise, use
    NotFoundError instead of CassandraException.  rely on THRIFT-378 to report internal errors.
    also, add field numbers to work around thrift bug generating python code.

0001
    move CF checking into CassandraServer.  begin to expose InvalidRequestException.  r/m
unused "del" cfmaps from batch methods.

(new libthrift.jar is built with the THRIFT-378 patch applied.)

> get_column() throws a TException when a column is missing. It should throw a special
exception (e.g, ColumnMissingException) to distinguish this case from a real failure.
