> I un-commented the -verbose:gc option in hbase-env.sh, which print out the gc 
> info.
> but when I use hbase zkcli to check zk, it can not connect to the server.
> the problem is zkcli uses "hbase 
> org.apache.hadoop.hbase.zookeeper.ZooKeeperMainServerArg" to get the 
> server_arg in the script hbase. when gc verbose option is open, the output of 
> ZooKeeperMainServerArg is with gc info, which masses up with server_arg. and 
> this is the reason stop zkcli working.
> I think the easiest way to fix this is to trim the gc info out of server_arg 
> in the hbase script.
