Description

Seeing the following from container log

Verified on MapR-4.1 and MapR-5.0.

MapR loads native libraries using class com.mapr.fs.ShimLoader. During the startup of Explore container, Twill launcher will first load the MapR native libraries. Since Explore uses a different classloader than the Twill launcher, com.mapr.fs.ShimLoader would get loaded again by Explore classloader, thus leading to duplicate definition. The fix is to load only one copy of com.mapr.fs.ShimLoader.

i've also backed up application_1442748581431_0015 container logs to /root/application_1442748581431_0015
