Subject [jira] Commented: (HADOOP-1114) bin/hadoop script clobbers CLASSPATH
Date Tue, 10 Apr 2007 21:43:32 GMT

Doug Cutting commented on HADOOP-1114:
--------------------------------------

> I accept that using CLASSPATH for dependencies is fragile and hacky, I'm not sure why
HADOOP_CLASSPATH is any different.

It's a bit less fragile, since it won't conflict with every other Java application in the
world, only with other Hadoop-based applications.  That's all.  For example, I've seen Windows
installers that set CLASSPATH to include lots of stuff that we wouldn't want on Hadoop's class
path.

> The bin/hadoop script distributed with hadoop clobbers the user's CLASSPATH.  This prevents
ad-hoc appending to the CLASSPATH.
