> PigStorage uses commons-cli to parse options. The CommandLineParser is stored as a static member. This can cause issues when two threads instantiate PigStorage at the same time, since CommandLineParser stores state in a non-thread-safe way.
> OptionBuilder, used in populateValidOptions(), is also not thread safe, as it stores its state in static members.
