Rename existing .bz files to .bz2 files. 2. Update scripts to read/write files with bz2 extension || This change is due to the fact that Text{Input/Output}Format only supports bz2 extension || || Switching to Hadoop's local mode || Local Mode || Low || None || Main change is 10-20x performance slowdown. Also, local mode now uses the same UDF interfaces to execute UDFs as the MR mode. || || Removing support for Load-Stream or Stream-Store optimization || Streaming || Low to None || None || This feature was never documented so it is unlikely it was ever used ||
