Description

Exporting default GC options in HBASE_OPTS from hbase-env.sh by default can interfere with some deployment scenarios. We probably shouldn't be doing that.

Noticed this when using scripts to set up EC2 test clusters for G1 GC. Having "-XX:+UseConcMarkSweepGC" on the command line in that case will cause the JVMs to fail to launch.
