Johan Oskarsson updated CASSANDRA-1050: --------------------------------------- Attachment: CASSANDRA-1050.patch This patch for trunk should help with the problem. Run ant gen-thrift-java as the generated code is not in the patch. I ran the word count test and that worked, have not had time to try it in the scenario described in the ticket though. > Too many splits for ColumnFamily with only a few rows > ----------------------------------------------------- > > Key: CASSANDRA-1050 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1050 > Project: Cassandra > Issue Type: Bug > Components: Hadoop > Affects Versions: 0.6 > Reporter: Joost Ouwerkerk > Fix For: 0.6.2 > > Attachments: CASSANDRA-1050.patch > > > ColumnFamilyInputFormat creates splits for the entire Keyspace. If one > ColumnFamily has 100 Million rows and another has only 100 rows, the number > of splits will be the 1,526 (assuming 64k rows per split) for either one, > since it is based on the total number of unique keys across the whole > keyspace, and not on the number of rows in the ColumnFamily. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
