raghavgautam/tramp-hdfs: Browser HDFS in Emacs using Tramp

Browse HDFS(Hadoop Distributed File System) in Emacs using Tramp.

Put this somewhere in your init file. Eg. ~/.emacs or ~/.emacs.d/init.el

It uses hdfs rest api/webhdfs which is supported in hadoop 1 & 2. The syntax to open file in hdfs is just like opening file over tramp.

Here, root is the user that you want to use, node-1 is the name of the hadoop server. As a general advice refrain from using superuser accounts like hdfs, hadaoop.

• Directory browsing
• Opening files
• Deleting files/directories

• The server must support webhdfs

• Manually: Download tramp-hdfs.el and add the location to load path.
• Through melpa: Ensure you have melpa in your package-archives (see Melpa Installation). Then, M-x package-install [RET] tramp-hdfs.

docker run -it --rm -v `pwd`:/root/.emacs.d silex/emacs

• Test assume a running HDFS instance at host "node-1". You will need to map this name to your actual instance via /etc/hosts or some other mechanism.

docker run -it --rm -v `pwd`:/root/.emacs.d silex/emacs --batch -l ert -l /root/.emacs.d/tramp-hdfs.el -l /root/.emacs.d/tramp-hdfs-tests.el -f ert-run-tests-batch-and-exit

• No support for writing/modification of files.
• No support for acls.
