Subject [jira] [Commented] (CASSANDRA-5803) Support pre-1.2 CQL3 tables in Pig
Date Mon, 29 Jul 2013 15:27:48 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-5803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13722535#comment-13722535
] 

Jonathan Ellis commented on CASSANDRA-5803:
-------------------------------------------

Same comment as on CASSANDRA-5800: the right fix is to propagate the column rename e.g. in
SystemTable.upgradeSystemData.  Then we don't have to keep adding special case hacks everywhere.

> Pre-1.2 release CQL3 table stores the key in system.schema_columnfamilies key_alias column
which is different from 1.2 release. We should support it in CqlPagingRecordReader as well.
