Eric Lin created SQOOP-3042:
-------------------------------
Summary: 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.
