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 CLASSPATH of spawned process.

> 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.
