Chris Nauroth commented on HADOOP-9450: --------------------------------------- Nicholas, thank you for the review. Harsh, it looks like we are good to commit now. > HADOOP_USER_CLASSPATH_FIRST is not honored; CLASSPATH is PREpended instead of > APpended > -------------------------------------------------------------------------------------- > > Key: HADOOP-9450 > URL: https://issues.apache.org/jira/browse/HADOOP-9450 > Project: Hadoop Common > Issue Type: Bug > Components: scripts > Reporter: Mitch Wyle > Assignee: Harsh J > Attachments: HADOOP-9450-branch-1.patch, > HADOOP-9450-branch-1-win.patch, HADOOP-9450.patch, HADOOP-9450.patch > > > 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. -- This message is automatically generated by JIRA.
