Hi Mesos dev: I'm now trying to use gdb-mesos-master.sh to debug mesos master but found that I cannot hit my break point, can someone help to see if there are something wrong with my steps?
The following are my steps: *1) Start gdb-mesos-master.sh* root@devstack007:/home/gyliu/src/mesos/m1/mesos/build# ./bin/gdb-mesos-master.sh --ip=9.111.242.143 --work_dir=/var/lib/mesos --log_dir=/root/mesos-log GNU gdb (Ubuntu 7.7.1-0ubuntu5~14.04.2) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.
