        接上篇，【日常Exception】第二十九回：Flink启动异常之java.net.UnknownHostException: xxxx: Name or service not knownn

之后，又报出了一个如下问题：

2、解决办法

        进入flink的配置文件目录，我的是：/usr/local/flink/conf，使用如下命令：

vim  flink-conf.yaml

        将jobmanager.memory.process.size 、jobmanager.memory.process.size 、taskmanager.memory.flink.size ，3个配置的值更改大一些，如：

jobmanager.memory.process.size: 2728m

taskmanager.memory.flink.size: 2280m

        第一个配置我没改，有需要的自行调整。。。然后重启flink，以及重启flink内需要运行的服务，如此就可以解决以上异常啦。。。
