[jira] [Created] (PIG-3988) PigStorage: CommandLineParser is not thread safe

Travis Woodruff created PIG-3988:
------------------------------------

             Summary: PigStorage: CommandLineParser is not thread safe
                 Key: PIG-3988
                 URL: https://issues.apache.org/jira/browse/PIG-3988
             Project: Pig
          Issue Type: Bug
    Affects Versions: 0.13.0
            Reporter: Travis Woodruff
            Assignee: Travis Woodruff
            Priority: Minor
             Fix For: 0.13.0


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.
