exist
-------------------------------------------------------------------------------------
Key: MAPREDUCE-3100
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3100
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: distcp
Affects Versions: 0.20.205.0
Reporter: Arpit Gupta
bash-3.2$ bin/hadoop --config HADOOP_CONF_DIR distcp -i
hftp://NN_HOST:50070/input_path hftp://NN_HOST:50070/output_path

does not exist.
With failures, global counters are inaccurate; consider running with -i

The same command works if instead of hftp default filesystem (hdfs) is used. It
creates the dir if it does not exist. We should do the same for hftp. I also
suspect that we have this issue with webhdfs.
