1.11 snapshot： Name or service not knownname localhost and taskMgr not started

1 Clone the 1.11 snapshot repository

2 Build it on windowns 

3 Scp the flink-dist/target/flink-1.11-SNAPSHOT-bin/flink-1.11-SNAPSHOT dir to a CentOS  server

4 ./bin/start-cluster.sh on the CentOS server 

There's message: 

Starting cluster.

Starting standalonesession daemon on host test_3.6.

: Name or service not knownname localhost

Only the jobMgr is started. The taskMgr not start 

Any insight on this？

Thanks

Hi Lei,

Could you check whether the hostname 'localhost' is available on your CentOS machine? This is usually defined in "/etc/hosts".

You can also try to modify the slaves file, replacing 'localhost' with '127.0.0.1'. The path is: <FLINK_DIR>/conf/slaves

• localhost is available on my CentOS machine.  I can start the cluster(including taskMgr) with start-cluster.sh when using flink-1.10 release tgz package
• change the slave file localhost to 127.0.0.1 can resolve the problem. But it request the password of the host.
• Not change  slave file, i can first start-cluster(only job manager started). And then “taskmanager.sh start“  to start the taskMgr. No password needed.

Thanks,
Lei
