我们以前在flink机器上使用rhel。我现在正在把它们转移到ubuntu上。当我启动任务管理器时，它无法通过以下消息连接到作业管理器-

2020-01-16 10:54:42,777 INFO  org.apache.flink.runtime.util.LeaderRetrievalUtils            - Trying to select the network interface and address to use by connecting to the leading JobManager.
2020-01-16 10:54:42,778 INFO  org.apache.flink.runtime.util.LeaderRetrievalUtils            - TaskManager will try to connect for 10000 milliseconds before falling back to heuristics
2020-01-16 10:54:52,780 WARN  org.apache.flink.runtime.net.ConnectionUtils                  - Could not find any IPv4 address that is not loopback or link-local. Using localhost address.

机器上的网络接口如下所示-

ens5: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 9001
        inet 10.16.75.30  netmask 255.255.255.128  broadcast 10.16.75.127

        TX packets 9562  bytes 1596138 (1.5 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

注意：在rhel上，主要网络接口是eth0。这就是问题所在吗？
