在搭建kudu分布式集群的时候，设置了两个kudu master节点，在两台节点的配置文件/etc/kudu/conf/master.gflagfile中进行了如下配置：
# Do not modify these two lines. If you wish to change these variables,
# modify them in /etc/default/kudu-master.
--fromenv=rpc_bind_addresses
--fromenv=log_dir
--fs_wal_dir=/var/lib/kudu/master
--fs_data_dirs=/var/lib/kudu/master
--default_num_replicas=1
--master_addresses=node1:7051,node2:7051
当启动 service kudu-master start 之后，发现master并没有启动起来，web UIhttp://node1:8051/masters 打不开。
之后查询日志发现有如下报错：
