For distcp you are providing 2 paths, source and target files/directories, both on HDFS of respective clusters. With some <A href="http://henning.kropponline.de/2015/03/15/distcp-two-ha-cluster/">more settings</A> you can refer to NN name service, meaning that you don't need to care which NN is active.</P> Mon, 10 Oct 2016 08:21:51 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Is-the-DistCp-NameNode-path-the-active-HDFS-NameNode-or-the/m-p/122114#M43124 pminovic 2016-10-10T08:21:51Z
