RE: hdfs-site.xml change must restart datanode?

Hi yaoxiaohua,
Use "dfs.datanode.max.transfer.threads" instead of "dfs.datanode.max.xcievers (deprecated)"..Yes, you need to restart the datanode.
Reference for deprecated properties:https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-common/DeprecatedProperties.html

Thanks And RegardsBrahma Reddy Battula
