Chris Nauroth commented on HADOOP-9450:
---------------------------------------
+1 for the patch. I tested successfully on Windows. Thanks for the patch,
Harsh!
I don't think it's important to keep the old HADOOP_CONF_DIR behavior. As you
pointed out, other Hadoop projects like Pig have already changed to the
behavior of your patch.
Shall we do a branch-1 patch too? Mitch's comments mentioned line numbers that
seem to be for the 1.x line.
> HADOOP_USER_CLASSPATH_FIRST is not honored; CLASSPATH is PREpended instead of
> APpended

> On line 133 of the hadoop shell wrapper, CLASSPATH is set as:
> CLASSPATH=${CLASSPATH}:${HADOOP_CLASSPATH}
> Notice that the built-up CLASSPATH, along with all the libs and unwanted JARS
> are pre-pended BEFORE the user's HADOOP_CLASSPATH. Therefore there is no way
> to put your own JARs in front of those that the hadoop wrapper script sets.
> We propose a patch that reverses this order. Failing that, we would like to
> add a command line option to override this behavior and enable a user's JARs
> to be found before the wrong ones in the Hadoop library paths.
> We always welcome your opinions.
