Travis Woodruff updated PIG-3988:
---------------------------------
Release Note: (was: This patch moves the option parsing members to local
variables in the constructor, since that's the only place they're used. Since
the CommandLineParser is no longer static, access by multiple threads is no
longer an issue.
It also removes use of the OptionBuilder class and configures the Option via
setters instead.
)
> PigStorage: CommandLineParser is not thread safe

>
> 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.
