Unable to load native-hadoop library for your platform

I am using Rancher for manage an environment , I am using Hadoop + Yarn (Experimental) for flink and zookeeper in rancher .

I am trying to configure the hdfs on the flink-conf.yaml.
This is the changes that I made in connection to Hdfs :

  1. fs.hdfs.hadoopconf: /etc/hadoop
  2. recovery.zookeeper.storageDir: hdfs://:8020/flink/recovery
  3. state.backend.fs.checkpointdir: hdfs://:8020/flink/checkpoints

And I get an error that say that :

2016-09-06 14:10:44,965 WARN org.apache.hadoop.util.NativeCodeLoader - Unable to load native-hadoop library for your platform… using builtin-java classes where applicable

What I did wrong ?

Best regards
