Final answer:
A) To simplify Sqoop command-line parameters, use the --options-file argument to include parameters from a file or create a shell script with the commands for easier execution
Step-by-step explanation:
To simplify command-line parameters for a Sqoop invocation, one effective approach is to use the --options-file command line argument. This argument allows users to specify a file that contains Sqoop options and arguments. By placing all the repetitive and complex command-line arguments into this file, the command line becomes simpler and more manageable. Another way to simplify Sqoop command-line parameters, although not mentioned directly in the options, is to create a shell script or batch file that includes the required Sqoop commands. This allows you to execute the script with a single command instead of typing out all the parameters each time you run a Sqoop job.
Regarding the options provided:
- 'B. Include the --options-file command line argument.' is a correct option.
- 'D. Place the commands in a file.' can be interpreted as either creating an options file or a script, which is also correct in the context of simplifying command invocation.
However, 'A. Use the --import command line argument.' does not necessarily simplify the command-line parameters. This argument is specific to performing an import operation and unrelated to simplification. 'C. Run Sqoop using the vi editor.' is not relevant to simplifying command-line parameters and is more related to the choice of text editor.
