Runping Qi commented on HADOOP-622:
-----------------------------------


When the user's app depend some libbrary that use JNI, the corresponding .so files have to
be available.
One way is achieve this is thatthe user put the .so files in the lib subdir. When the tasktracker
launch the child, it adds the lib dir to the library path.

> This would be useful with caching. So you would be avble to say, cache file X and then
should be able to change the environment variable like PATH/LD_LIBRARY_PATH to include the
local path hwere the file was cached.
