```
public static boolean getKeepCommandFile(JobConf conf)
```
    Does the user want to keep the command file for debugging? If this is true, pipes will write a copy of the command data to a file in the task directory named "downlink.data", which may be used to run the C++ program under the debugger. You probably also want to set JobConf.setKeepFailedTaskFiles(true) to keep the entire directory from being deleted. To run using the data file, set the environment variable "mapreduce.pipes.commandfile" to point to the file.
    
    パラメータ:
    
    conf - the configuration to check
    
    戻り値:
