hdfs-site.xml change must restart datanode?

[yaoxiaohua]

Hi,

                Hadoop2.3cdh5.0.2

                I change hdfs-site.xml

                Update two properties value;

                dfs.datanode.max.xcievers 

                dfs.datanode.max.transfer.threads 

                I must restart the datanode process for this?

                Thanks very much!

 

Best Regards,

Evan Yao
