Flink本地模式启动时Task Managers启动失败

环境：

修改前

启动命令：/usr/local/src/flink-1.7.2

启动信息：Starting cluster.

Starting standalonesession daemon on host basic. Starting taskexecutor daemon on host basic. 终止命令：./bin/stop-cluster.sh

终止信息：

No taskexecutor daemon (pid: 3589) is running anymore on basic. No standalonesession daemon (pid: 3153) is running anymore on basic.

修改前页面信息：

原因分析：

因为虚拟机创建时使用的主机名为 basic，但是未在host文件中指定映射，故找不到对应的主机信息，无法启动

报错信息如下：

修改host文件：vim /etc/hosts

关闭集群重新启动即可：

[root@basic flink-1.7.2]# ./bin/stop-cluster.sh No taskexecutor daemon (pid: 7822) is running anymore on basic. No standalonesession daemon (pid: 7371) is running anymore on basic.

Starting cluster. [INFO] 1 instance(s) of standalonesession are already running on basic. Starting standalonesession daemon on host basic. Starting taskexecutor daemon on host basic. 启动成功后界面如下：

[INFO] 1 instance(s) of standalonesession are already running on basic. Starting standalonesession daemon on host basic. Starting taskexecutor daemon on host basic.
