Subject [jira] Commented: (HIVE-338) Executing cli commands into thrift server
Date Tue, 23 Jun 2009 16:32:07 GMT


Joydeep Sen Sarma commented on HIVE-338:

hmmm - the MapRedTask changes don't seem good to me ..

the conf variable that gets passed to MapRedTask is a shared global object i think. if we
set added jars into it - then delete jar command will not work.

also - -libjars is the proper way of passing jars to hadoop based commands. it also sets the
supplied jars into the sub-process's classpath - something that we depend on hadoop to do.
so if the execdriver subprocess needs to access (by any chance) classes in the added/aux jars
- then things will not work. bin/hive also uses -libjars to make sure jars are added to the
process classpath.

if the problem is primarily with the file:/ uri - why do we need the mapredtask changes?
