      Description

      The following pig script:
      b = load 'bad.input' using JsonLoader('a0: chararray');
      dump b;

      runs well for the input:

      {"a": "good"}

      and fails the whole job for the following input (mallformed json)

      {"a", bad}

      I was expecting that it will just skip the line and go further.

      Getting this error:
      org.codehaus.jackson.JsonParseException: Unexpected character ('g' (code 103)): was expecting comma to separate OBJECT entries
