Dear all, My Flink Job reads from a kafka topic and store the data in a RocksDB state backend, in order to make use of the queryable state. I'm able to run the job and query the state in my local machine. But when deploying on the cluster, I'm getting the below error:
Caused by: org.apache.flink.runtime.client.JobExecutionException: Job execution failed. at org.apache.flink.runtime.jobmanager.JobManager$$anonfun$handleMessage$1$$anonfun$applyOrElse$6.apply$mcV$sp(JobManager.scala:900) at org.apache.flink.runtime.jobmanager.JobManager$$anonfun$handleMessage$1$$anonfun$applyOrElse$6.apply(JobManager.scala:843) at org.apache.flink.runtime.jobmanager.JobManager$$anonfun$handleMessage$1$$anonfun$applyOrElse$6.apply(JobManager.scala:843) at scala.concurrent.impl.Future$PromiseCompletingRunnable.liftedTree1$1(Future.scala:24) at scala.concurrent.impl.Future$PromiseCompletingRunnable.run(Future.scala:24) at akka.dispatch.TaskInvocation.run(AbstractDispatcher.scala:40) at akka.dispatch.ForkJoinExecutorConfigurator$AkkaForkJoinTask.exec(AbstractDispatcher.scala:397) at scala.concurrent.forkjoin.ForkJoinTask.doExec(ForkJoinTask.java:260) at scala.concurrent.forkjoin.ForkJoinPool$WorkQueue.runTask(ForkJoinPool.java:1339) at scala.concurrent.forkjoin.ForkJoinPool.runWorker(ForkJoinPool.java:1979) at scala.concurrent.forkjoin.ForkJoinWorkerThread.run(ForkJoinWorkerThread.java:107) Caused by: java.lang.IllegalStateException: Could not initialize keyed state backend. at org.apache.flink.streaming.api.operators.AbstractStreamOperator.initKeyedState(AbstractStreamOperator.java:286) at org.apache.flink.streaming.api.operators.AbstractStreamOperator.initializeState(AbstractStreamOperator.java:199) at org.apache.flink.streaming.runtime.tasks.StreamTask.initializeOperators(StreamTask.java:666) at org.apache.flink.streaming.runtime.tasks.StreamTask.initializeState(StreamTask.java:654) at org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:257) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:655) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.Exception: Could not load the native RocksDB library at org.apache.flink.contrib.streaming.state.RocksDBStateBackend.ensureRocksDBIsLoaded(RocksDBStateBackend.java:483) at org.apache.flink.contrib.streaming.state.RocksDBStateBackend.createKeyedStateBackend(RocksDBStateBackend.java:235) at org.apache.flink.streaming.runtime.tasks.StreamTask.createKeyedStateBackend(StreamTask.java:785) at org.apache.flink.streaming.api.operators.AbstractStreamOperator.initKeyedState(AbstractStreamOperator.java:277) ... 6 more Caused by: java.lang.UnsatisfiedLinkError: /data/hadoop/tmp/rocksdb-lib-32bc6a5551b331596649309a808b287d/librocksdbjni-linux64.so: /data/hadoop/tmp/rocksdb-lib-32bc6a5551b331596649309a808b287d/librocksdbjni-linux64.so: ELF file data encoding not big-endian (Possible cause: endianness mismatch) at java.lang.ClassLoader$NativeLibrary.load(Native Method) at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1941) at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1824) at java.lang.Runtime.load0(Runtime.java:809) at java.lang.System.load(System.java:1086) at org.rocksdb.NativeLibraryLoader.loadLibraryFromJar(NativeLibraryLoader.java:78) at org.rocksdb.NativeLibraryLoader.loadLibrary(NativeLibraryLoader.java:56) at org.apache.flink.contrib.streaming.state.RocksDBStateBackend.ensureRocksDBIsLoaded(RocksDBStateBackend.java:460) I have tried setting the rocksDB state backend at cluster level and job level. when it is set at job level, I have provided it as a shaded dependency. I have tried compiling the code on the host cluster machine as well. I get the same error in all the cases. ELF file data encoding not big-endian (Possible cause: endianness mismatch) How can I solve this error? Thanks in advance Ziyad
