------------------------------

             Summary: hplsql should add enterGlobalScope func to UDF
                 Key: HIVE-15849
                 URL: https://issues.apache.org/jira/browse/HIVE-15849

          Issue Type: Bug
          Components: hpl/sql
    Affects Versions: 2.2.0

code in Udf.java
{quote}
    if (exec == null) {
      exec = new Exec();
      exec.enterGlobalScope();
      String query = queryOI.getPrimitiveJavaObject(arguments[0].get());
      String[] args = { "-e", query, "-trace" };
      try {
        exec.setUdfRun(true);
        exec.init(args);
      } catch (Exception e) {
        throw new HiveException(e.getMessage());
      }
    }
    if (arguments.length > 1) {
      setParameters(arguments);
    }
    Var result = exec.run();
    if (result != null) {
      return result.toString();
    }
{quote}
