Subject [jira] [Updated] (CASSANDRA-3045) Update ColumnFamilyOutputFormat to use new bulkload API
Date Fri, 04 Nov 2011 19:23:51 GMT


Brandon Williams updated CASSANDRA-3045:

    Attachment: 0001-Remove-gossip-SS-requirement-from-BulkLoader.patch

Posting what I have with this approach, though a bit rough.  No output format yet, just converts
the loader to not require gossip.  There's a catch, however.  Since FileStreamTask uses a
socket for every file, when all the files are done we don't have a socket left to acknowledge
the session with, so the loading hangs at 'Waiting for targets to rebuild indexes' forever.
 We can do major streaming surgery on FST, or possibly wait for CASSANDRA-3112 to get past
