Classpath

Hi. could you share information about storm classloader implementation.
Does storm load a separate classpath for each topology (jar)?
Can 2 topology collide with each other if they have a dependency on library
with different version?


Thank you.

Generally, all topologies have the same class path: 1) ${STORM.DIR}/conf  2)${STORM.DIR}/lib

when topology needs to rely on different version,  you can package dependent jar in  your topology jar and submit separately.
