Hi Till, Can you tell when do I receive below error message?
2018-10-13 03:02:01,337 ERROR org.apache.flink.runtime.rest.handler.taskmanager.TaskManagersHandler - Could not retrieve the redirect address. java.util.concurrent.CompletionException: org.apache.flink.runtime.rpc.exceptions.FencingTokenException: Fencing token not set: Ignoring message LocalFencedMessage(8b79d4540b45b3e622748b813d3a464b, LocalRpcInvocation(requestRestAddress(Time))) sent to akka.tcp://flink@127.0.0.1:50010/user/dispatcher because the fencing token is null.

In your setup (not running on top of Yarn or Mesos) you need to set the jobmanager.rpc.address such that the JM process knows where to bind to. The other components use ZooKeeper to find out the addresses. The other properties should not be needed. 3. You can take a look at the ZooKeeper leader latch node. Alternatively, you can take a look at the address to which you are redirected when accessing the web UI. 4. https://ci.apache.org/projects/flink/flink-docs-master/ops/security-ssl.html<https://clicktime.symantec.com/a/1/czwzBd85jiO-rQDJ8_mMefpd3vfTIKXunaLv5x3byJ0=?d=mPS97wozxPvF4EdXANMCpE7ERTYx_MNjBfkSDx4tF1lQcEIakYIujzTvjOPtkLS1aSEPhxKGiUWI5HVgpZqIYInAwLRaKCbZg1D_lAGXbUC3Vi43DtbJ09d0ZH04UZ5-kyFlDoSrrED_73X8GSB3rUGey5afFf4TFAgJPIKz9GoAPlZInMKklM9WuqsWblPZjTTCgsp85nImxyw2Cbn7NnrluemBf_uC-L7L_bv38RLohs-_Hk62T6F9Q_n9Pr9-c0XQB8X6XkEjJRFcchqBkuNED5pePHFYu2_RSIElSTDUKPXkeWMX5p_oDIJr3MYl9H6trEgz-b8-K2E7KtIGreBUgLYfBUKJ-lPGjQf8Eq2GjKw2wIG1JPIj5eppc3PbeYrllgNPN24wh8GWClBwTTgvXvXNEV4imz2GvD43P2AKWGynAmIzfjnK190%3D&u=https%3A%2F%2Fci.apache.org%2Fprojects%2Fflink%2Fflink-docs-master%2Fops%2Fsecurity-ssl.html> Cheers, Till On Sat, Oct 6, 2018 at 5:57 PM Samir Tusharbhai Chauhan <samir.tusharbhai.chau...@prudential.com.sg<mailto:samir.tusharbhai.chau...@prudential.com.sg>> wrote: Hi Till, Thanks for identifying the issue. My cluster is up and running now. I have few queries. Can you have to anwer that? 1. Do I need to set below properties in my cluster? jobmanager.rpc.address rest.address rest.bind-address jobmanager.web.address 1. Is there anything I should be take care while setting it up? 2. How do I know which job manager is active? 3. How do I secure my cluster?

It looks to me as if the TM had an outdated fencing token (an outdated leader session id) with which it contacted the ResourceManager. This can happen and the TM should try to reconnect to the RM once it learns about the new leader session id via ZooKeeper. You could, for example check in ZooKeeper that it contains the valid leader information.
