背景

部署好Hadoop集群后，发现native-hadoop不可用。

root@test-hdfs-client-7956fbd4f9-gxsf4:/# hdfs dfs -ls /
2019-07-10 12:36:20,232 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

drwxr-xr-x   - root supergroup          0 2019-07-09 08:02 /user

调查

为了获取更多信息，开启debug日志。在$HADOOP_CONF_DIR/log4j.properties中添加如下行：

log4j.logger.org.apache.hadoop.util.NativeCodeLoader=DEBUG

继续执行hdfs命令

root@test-hdfs-client-7956fbd4f9-gxsf4:/# hdfs dfs -ls /
