Answer 1

的问题得到解决变化环境变量CASSANDRA_SEED_COUNT，因为默认情况下CASSANDRA_SEED_COUNT = 2并且我配置了app.json以仅使用一个节点部署cassandra（CASSANDRA_NODE_COUNT = 1）。

如果您尝试使用所有默认配置，它可以很好地与环境变量一起工作，但只有您需要确保mesos群集中有3个或更多的从属节点可用。

# The number of nodes in the cluster (default 3) 
CASSANDRA_NODE_COUNT=3 

# The number of seed nodes in the cluster (default 2) 
# set this to 1, if you only want to spawn one node 
CASSANDRA_SEED_COUNT=2
