> Key: SQOOP-3042
> URL: https://issues.apache.org/jira/browse/SQOOP-3042
> Project: Sqoop
> Issue Type: Bug
> Affects Versions: 1.4.6
> Reporter: Eric Lin
> Assignee: Eric Lin
> Priority: Critical
> Labels: patch
> Attachments: SQOOP-3042.1.patch, SQOOP-3042.2.patch,
> SQOOP-3042.4.patch, SQOOP-3042.5.patch, SQOOP-3042.6.patch, SQOOP-3042.7.patch
>
>
> 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.
