Eric Lin commented on SQOOP-3042: --------------------------------- I am currently working on the JIRA and will upload the patch soon. > Sqoop does not clear compile directory under /tmp/sqoop-<username>/compile > automatically > ---------------------------------------------------------------------------------------- > > Key: SQOOP-3042 > URL: https://issues.apache.org/jira/browse/SQOOP-3042 > Project: Sqoop > Issue Type: Bug > Reporter: Eric Lin > Priority: Critical > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
