> Hive two types of data files - flat files and sequencefiles. Syntax should reflect this. Currently the 'compressed' keyword is used to choose sequencefile format - but does not actually compress the files. this is misleading. In addition - flat files can also be compressed.
> Proposal is to replace 'compressed' with 'sequencefile'. And compression options should be applied from standard hadoop way of specifying whether output should be compressed (''mapred.output.compress') - ie. session options. (session options will also define codec etc.). default file format and compression options can be specified in conf file.
