[jira] [Created] (MESOS-3351) nextSlaveId in master was not updated when recover

Klaus Ma created MESOS-3351:
-------------------------------

             Summary: nextSlaveId in master was not updated when recover
                 Key: MESOS-3351
                 URL: https://issues.apache.org/jira/browse/MESOS-3351
             Project: Mesos
          Issue Type: Bug
          Components: master
         Environment: Mac OS (Darwin da-macbookair.cn.ibm.com 14.5.0 Darwin Kernel Version 14.5.0: Wed Jul 29 02:26:53 PDT 2015; root:xnu-2782.40.9~1/RELEASE_X86_64 x86_64)
            Reporter: Klaus Ma
            Assignee: Klaus Ma


When a slave register to master, master will generate a slave ID for it by slaveInfo.id + "-S" + nextSlaveId (in master.cpp) to avoid duplicate slaveInfo.id. But if master failover, nextSlaveId was reset to 0 which may trigger duplicated slaveId between old slave & new slave.

For now, it's only reproduced in Mac OS unstably, and can NOT reproduce in Ubuntu; not sure the other OS.
