Zhe Zhang commented on HADOOP-12615:
Thanks Wei-Chiu. +1 on the latest patch pending a couple of minor suggestions:
# In {{ThreadUtil#getResourceAsStream}} I suggest we throw an exception when
current thread's CL is null. Pls let me know you have an explanation that the
same input stream will be returned from ThreadUtil's CL.
# Similarly, I suggest we remove the change in {{Server}}, or change it to
throw an exception. Otherwise it will possibly use the CL of ThreadUtil.
{code}
if (is == null) {
throw new IOException("Can not read resource file '" +
resourceName + "'");

Zhe Zhang commented on HADOOP-12615:
Thanks Steve for the suggestion; good point.
Thank you for the update Wei-Chiu. I have a few questions/comments.
# I'm not sure if {{cl = ThreadUtil.class.getClassLoader()}} is the right
behavior. Could you explain why we can use the CL of {{ThreadUtil}} to replace
the CL of the current thread?
# In {{MiniKMS}}, better make the following 2 segments consistent. They should
both use a try-finally structure, or neither. Actually I don't think we need
the try-finally: in case of IOException, {{is}} remains null anyway.
{code}
if (!aclsFile.exists()) {
InputStream is =
ThreadUtil.getResourceAsStream("mini-kms-acls-default.xml");
{code}
{code}
InputStream is = null;
OutputStream os;
try {
is = ThreadUtil.getResourceAsStream("kms-webapp/WEB-INF/web.xml");
os = new FileOutputStream(new File(webInf, "web.xml"));
IOUtils.copy(is, os);
} finally {
IOUtils.closeQuietly(is);
IOUtils.closeQuietly(is);
}
{code}
# Also, {{is}} is closed twice in the above. A typo with {{os}}?
# The local variable {{is}} in {{TestKMSAudit.java}} doesn't look necessary?
How about keeping the original structure but use the new
{{getResourceAsStream}} method?
# {{MiniKdc}} still uses the old {{getResourceAsStream}}

Zhe Zhang commented on HADOOP-12615:
Thanks Wei-Chiu for the fix! A few questions/comments
# We should avoid wildcard imports: {{import java.io.*;}}
# Could you add to the description the failed test you saw? I think we should
only throw exception for the NPE that showed up. For some other places, I
suspect some logics could handle a null inputstream already. For example, looks
like {{PropertyConfigurator.configure(in)}} does nothing if {{in}} is null.
