Hello, I'm writing this email, because, I spent one hour to look for a cp command in the webhdfs API (in fact, I'm using HTTPFS, but I think it's the same).
This command is implemented in the "hdfs dfs" command line client (and I'm using this command), but, I can't find it on the webhdfs REST API. I thought that webhdfs is an implementation of the Filesystem object ( https://hadoop.apache.org/docs/r2.6.1/api/org/apache/hadoop/fs/FileSystem.html). I checked at the Java API and I haven't found any cp command. The only java cp command is on the FileUtil Object ( https://hadoop.apache.org/docs/stable/api/org/apache/hadoop/fs/FileUtil.html) and I'm not sure that it work identicaly than "hdfs dfs -cp" command. I also checked at the Hadoop JIRA, and I found nothing : https://issues.apache.org/jira/browse/HADOOP-9417?jql=project%20%3D%20HADOOP%20AND%20(text%20~%20%22webhdfs%20copy%22%20OR%20text%20~%20%22webhdfs%20cp%22) is there a way to execute a cp command through a REST API ? All my best, Jérôme
