Hadoop 如何单独更改配置单元的HDFS复制因子

我们当前的HDFS群集的复制系数为1。但为了提高性能和可靠性（节点故障），我们希望仅将配置单元中间文件（Hive.exec.scratchdir）复制系数增加到5。有可能实现这一点吗

问候,，

-setrep

是否对您有帮助

setrep

用法：

hadoop fs -setrep [-R] [-w] <numReplicas> <path>

示例：

The -w flag requests that the command wait for the replication to complete. This can potentially take a very long time.

The -R flag is accepted for backwards compatibility. It has no effect.

hadoop fs -setrep -w 3 /user/hadoop/dir1

hadoop fs -setrep -R -w 100 /path/to/hive/warehouse
