> 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.
