HDFSTREE

This is a simple standalone tool that emulates the Unix 'tree' command in HDFS.

USAGE

To use it just copy the tool, add it to your path it's ready to use, it has 3 options:

  • -p: Specifies the root path. This is mandatory.
  • -l: Specifies that you want to use the local filesystem instead of HDFS:
  • -s: Specifies that you want to see the size (in human readable format) next to each directory.
  • -d: Specifies the maximum depth when displayin the tree.

some examples:

hdfstree -p /
This will print all the HDFS tree. This will take some time...

hdfstree -p /user/marc/ 
Print all the directories starting from /user/marc

hdfstree -l -p /Users/marc/Music -s 
Print all the directories in the /Users/marc/Music directory in the local filesystem and display the sizes. 

The output is pretty much like the unix tree command. Have an example:

BUILDING & SOURCE

Build is done with gradle. To create a ready to use script with the libraries just use:

gradle installApp

You'll get the executable script + the libraries in

hdfstree/build/install/hdfstree

just add this directory (hdfstree/build/install/hdfstree/bin) to your PATH variable and you are done, also, make sure you have the HADOOP_HOME environment variable set. The program will complain if you don't have it.
