Description

In an HA cluster env with nn1 (standby) and nn2 (active), "hdfs dfs -getmerge" of "hadoop fs -getmerge" can fail. It references the wrong NameNode (nn1 standby), instead of nn2 (active).

A work-around is to add "hdfs://<activeNameNodeHost>/", or "hdfs://<clusterName>/", to the start of the first parameter (source in hdfs).
