Re: FileSystem API - Moving files in HDFS
There is no FileSystem API to copy.
You could try
hadoop dfs -cp <src> <dest>

which basically reads the file and writes to new file.
The code for this is in FsShell.java

Subject: FileSystem API - Moving files in HDFS


I'd like to move and copy files from one directory in HDFS to another
one. I know there are methods in the Filesystem API that enable
copying files between the local disk and HDFS, but I couldn't figure
out how to do this between two paths both in HDFS. I think rename(Path
src, Path dest) can be used to move files, but copying still remains a
challenge to me. Any ideas?
