> After running sqoop, all the temp files generated by ClassWriter are left behind on disk,
so anyone can check those JAVA files to see the schema of those tables that Sqoop has been
interacting with. By default, the directory is under /tmp/sqoop-<username>/compile.
> In class org.apache.sqoop.SqoopOptions, function getNonceJarDir(), I can see that we
did add "deleteOnExit" on the temp dir:
> {code}
>     for (int attempts = 0; attempts < MAX_DIR_CREATE_ATTEMPTS; attempts++) {
>       hashDir = new File(baseDir, RandomHash.generateMD5String());
>       while (hashDir.exists()) {
>         hashDir = new File(baseDir, RandomHash.generateMD5String());
>       }
>       if (hashDir.mkdirs()) {
>         // We created the directory. Use it.
>         // If this directory is not actually filled with files, delete it
>         // when the JVM quits.
>         hashDir.deleteOnExit();
>         break;
>       }
>     }
> {code}
> However, I believe it failed to delete due to directory is not empty.
