Subject [jira] Commented: (HIVE-928) ScriptOperator does not set CLASSPATH of spawned process.

Namit Jain commented on HIVE-928:
---------------------------------

I wanted to know what does hadoop streaming do if I write a mapper in java - is the classpath
passed ?

In any case, I think it is a good idea to do so, but we should only add the JARs that were
added by the user.

> ScriptOperator does not set the CLASSPATH of the the spawned script process. 
> The practical implication of this is that Java JARs that are added using the "add JAR"
command 
> will not be accessible to TRANSFORM/MAP/REDUCE operators unless the user can guess the
> location of the JAR archive on each node.
