Hi Flink Dev, I am running flink on yarn from EMR and I was running this command to test an external savepoint flink savepoint 8c4c885c5899544de556c5caa984502d /mnt
The program finished with the following exception: org.apache.flink.runtime.leaderretrieval.LeaderRetrievalException: Could not retrieve the leader gateway at org.apache.flink.runtime.util.LeaderRetrievalUtils.retrieveLeaderGateway(LeaderRetrievalUtils.java:127) at org.apache.flink.client.program.ClusterClient.getJobManagerGateway(ClusterClient.java:645) at org.apache.flink.client.CliFrontend.getJobManagerGateway(CliFrontend.java:868) at org.apache.flink.client.CliFrontend.triggerSavepoint(CliFrontend.java:653) at org.apache.flink.client.CliFrontend.savepoint(CliFrontend.java:643) at org.apache.flink.client.CliFrontend.parseParameters(CliFrontend.java:1016) at org.apache.flink.client.CliFrontend.main(CliFrontend.java:1048) Caused by: java.util.concurrent.TimeoutException: Futures timed out after [10000 milliseconds] at scala.concurrent.impl.Promise$DefaultPromise.ready(Promise.scala:219) at scala.concurrent.impl.Promise$DefaultPromise.result(Promise.scala:223) at scala.concurrent.Await$$anonfun$result$1.apply(package.scala:107) at scala.concurrent.BlockContext$DefaultBlockContext$.blockOn(BlockContext.scala:53) at scala.concurrent.Await$.result(package.scala:107) at scala.concurrent.Await.result(package.scala) at org.apache.flink.runtime.util.LeaderRetrievalUtils.retrieveLeaderGateway(LeaderRetrievalUtils.java:125) ... 6 more 2017-05-22 19:50:10,330 INFO org.apache.flink.yarn.YarnClusterClient - Shutting down YarnClusterClient from the client shutdown hook 2017-05-22 19:50:10,330 INFO org.apache.flink.yarn.YarnClusterClient - Disconnecting YarnClusterClient from ApplicationMaster [hadoop@ip-10-202-4-24 flink]$ flink savepoint 8c4c885c5899544de556c5caa984502d /mnt Any clue what’s wrong? =============Notice to Recipient: This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain information that is confidential or legally privileged, and intended for the use of the individual or entity named above.
