Owen O'Malley commented on HDFS-905:
------------------------------------
This is looking good. I notice that you have some spurious whitespace changes
and a fair number of lines that go past 80 characters.
In FileChecksumServlets.java, you have:
{noformat}
+ final NameNode namenode = getUGI(request).doAs(new PrivilegedExceptionA
ction<NameNode>() {
+ @Override
+ public NameNode run() throws IOException {
+ return (NameNode)context.getAttribute("name.node");
+ }
+ });
{noformat}
but the context.getAttribute doesn't use the current user, it just pulls an
object out of a map setup when the jetty server started.
