Subject [jira] [Commented] (CASSANDRA-4755) Bulk loader won't work with CQL3
Date Sat, 20 Oct 2012 22:28:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13480847#comment-13480847

Aleksey Yeschenko commented on CASSANDRA-4755:
----------------------------------------------

Haven't dealt with BulkRecordWriter.External/BulkLoader.ExternalClient duplication. The attached
patch fixes the BulkLoader+CQL3 issue and does nothing beyond that.

Please create a new issue for removing the duplication (or tell me to create it) if you still
think it's worth the effort. But that would have a different priority compared to this issue,
so I've dealt with the bug first.

> Currently the bulk loader uses thrift to get the schema and validate it before bulk loading
a cf. Since we stopped returning cql3 cfs through describe_keyspaces, the bulk loader will
be unable to load those cfs.
> If we figure out/add a way to validate the schema over jmx, we could use that for getting
token ranges as well and drop thrift completely from the bulk loader.
> Another option might be querying system tables manually to validate things.
