Issue MESOS-5114: Flags::parse does not handle empty string correctly.
A missing default for quorum size has generated the following master config {code} MESOS_WORK_DIR="/var/lib/mesos/master" MESOS_ZK="zk://zk1:2181,zk2:2181,zk3:2181/mesos" MESOS_QUORUM= MESOS_PORT=5050 MESOS_CLUSTER="mesos" MESOS_LOG_DIR="/var/log/mesos" MESOS_LOGBUFSECS=1 MESOS_LOGGING_LEVEL="INFO" {code} This was causing each elected leader to attempt replica recovery. E.g. {{group.cpp:700] Trying to get '/mesos/log_replicas/0000000012' in ZooKeeper}} And eventually: {{master.cpp:1458] Recovery failed: Failed to recover registrar: Failed to perform fetch within 1mins}} Full log on one of the masters https://gist.github.com/clehene/09a9ddfe49b92a5deb4c1b421f63479e All masters and zk nodes were reachable over the network. Also once the quorum was configured the master recovery protocol finished gracefully.
