[jira] [Created] (CASSANDRA-6272) sstableloader data distribution
is broken since 1.2.10
Sam Tunnicliffe created CASSANDRA-6272:
------------------------------------------
Summary: sstableloader data distribution is broken since 1.2.10
Key: CASSANDRA-6272
URL: https://issues.apache.org/jira/browse/CASSANDRA-6272
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
Priority: Minor
Running sstableloader on 1.2.10+ results in radically different distribution compared with earlier versions. It looks as though the 'bare-bones' IndexSummary created in SSTR.loadForBatch is the cause (CASSANDRA-5555); because it contains only a single entry, we end up with the wrong segment of the index file in SSTR.getPosition (its position is always 0), so only the first segment of the index file is considered when searching for the range's position.
This doesn't affect 2.0/trunk
