The following page has been changed by DevarajDas: http://wiki.apache.org/lucene-hadoop/FAQ ------------------------------------------------------------------------------ * `io.sort.factor = 100` * `io.sort.mb = 200` * `io.file.buffer.size = 131072` - Interestingly, Sort performances on 1400 nodes and 2000 nodes are very much under control (sorting 14TB of data on a 1400-node cluster takes roughly the same time as it takes for sorting 20TB on 2000-node cluster). + + Sort performances on 1400 nodes and 2000 nodes are pretty good too - sorting 14TB of data on a 1400-node cluster takes 2.2 hours; sorting 20TB on a 2000-node cluster takes 2.5 hours. == 4. Do I have to write my application in Java? ==
