Title: Fix Hadoop 0.20, 0.21 compilation; improve handling of script dir

Current versions of Hadoop seem to support getFloat as part of jobConf and not getDouble:
https://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/conf/Configuration.html#getFloat(java.lang.String, float)

This pull request also improves the handling of the script directory as part of GenerateReplayScript. If the directory doesn't exist, it creates it. Otherwise, it confirms with the user before over-writing an existing directory.
