Review request for Sqoop, Boglarka Egyed and Szabolcs Vasas.
Changes
-------
updated src/docs to include the new parameter
Bugs: SQOOP-3042
https://issues.apache.org/jira/browse/SQOOP-3042
Repository: sqoop-trunk
Description
-------
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:
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;
}
}
However, I believe it failed to delete due to directory is not empty.

Testing
-------
I have tested manually. I have checked with a couple of other Java developers
and it turned out that it is not easy to add test for deleteOnExit, so I did
not add any test cases. The code path I changed does not seem to have test
coverage either. Let me know if I am wrong.
