Colin Patrick McCabe commented on HDFS-7186:
--------------------------------------------
Looks good.
{code}
+ $ hadoop trace -add -class org.htrace.impl.LocalFileSpanReceiver
-Chadoop.htrace.local-file-span-receiver.path=/tmp/htrace.out -host
192.168.56.2:9000
{code}
Since the namespace of LocalFileSpanReceiver might be changing soon, I'd prefer
to tell people to use {{hadoop trace -add -class LocalFileSpanReceiver}} (i.e.,
have the system automatically add the namespace). That way it will work even
after we move {{LocalFileSpanReceiver}}.
