-------------------------------------

             Summary: Do not set default GC options in hbase-env.sh
                 Key: HBASE-8926
                 URL: https://issues.apache.org/jira/browse/HBASE-8926
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.98.0, 0.95.2, 0.94.10
            Reporter: Andrew Purtell
            Assignee: Andrew Purtell
            Priority: Trivial


Exporting 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.
