-------------------------------
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.
