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

             Summary: Not enough error message for debugging when parameters missing
                 Key: SQOOP-3135
                 URL: https://issues.apache.org/jira/browse/SQOOP-3135
             Project: Sqoop
          Issue Type: Improvement
    Affects Versions: 1.4.6
            Reporter: Eric Lin
            Assignee: Eric Lin


Run the following sqoop command:

{code}
sqoop job --create test -- import --connect jdbc:mysql://localhost/test --username root --password $pass --target-dir /tmp/test10 -m 1 --driver com.mysql.jdbc.Driver  --table test
{code}

Due to $pass is not set, command will fail with the following error:

{code}
16/12/21 05:48:32 INFO sqoop.Sqoop: Running Sqoop version: 1.4.7-SNAPSHOT
16/12/21 05:48:33 ERROR tool.JobTool: Error parsing arguments to the job-specific tool.
16/12/21 05:48:33 ERROR tool.JobTool: See 'sqoop help <tool>' for usage.
{code}

This is not informative, by checking the code in JobTool class:

{code}
    // Now feed the arguments into the tool itself.
    try {
      childOptions = childTool.parseArguments(parseableChildArgv,
          null, childOptions, false);
      childTool.appendArgs(extraChildArgv);
      childTool.validateOptions(childOptions);
    } catch (ParseException pe) {
      LOG.error("Error parsing arguments to the job-specific tool.");
      LOG.error("See 'sqoop help <tool>' for usage.");
      return 1;
    } catch (SqoopOptions.InvalidOptionsException e) {
      System.err.println(e.getMessage());
      return 1;
    }
{code}

The ParseException pe's message has been dropped, we should print out the message in the exception so that more meaningful message will be printed.
