I use the follow code to set RocksDBStateBackend and it option, it can run
correctly locally, but can't be submitted to cluster.
Main.class:
public static void main() {
final StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
RocksDBStateBackend rocksDBBackEnd = new
RocksDBStateBackend("file:///Users/zsh/tmp/rocksdb");
rocksDBBackEnd.setPredefinedOptions(PredefinedOptions.DEFAULT);
rocksDBBackEnd.setOptions(new MRocksDBFactory());
env.setStateBackend(rocksDBBackEnd);
...............
env.execute(jobName);
}
MRocksDBFactory.class:
public class MRocksDBFactory implements OptionsFactory {
@Override
public DBOptions createDBOptions(DBOptions currentOptions) {
return currentOptions;
}
@Override
public ColumnFamilyOptions createColumnOptions(ColumnFamilyOptions
currentOptions) {
return currentOptions;
}
}
The exception info in jobmanager.log look like below:
