Hadoop Copy Options
distcp: Distributed copy to move data between clusters, used for backup and recovery:
put: Copy file(s) from local file system to destination file system. It can also read from “stdin” and writes to destination file system:
hadoop dfs –put weather.txt hdfs://<target Namenode>
hadoop dfs –copyFromLocal weather.txt hdfs://<target Namenode>
hadoop distcp hdfs://<source NN> hdfs://<target NN>
