It completes commands, switches and **HDFS paths**. 4 | The latter is our main contribution to the script which has a history from 5 | [facebook](https://github.com/facebookarchive/hadoop-20/tree/master/src/contrib/bash-tab-completion) 6 | and [guozheng](https://github.com/guozheng/hadoop-completion). 7 | 8 | ## Usage 9 | 10 | Simplest way to use it, is to source it: 11 | 12 | source /path/to/hadoop-completion.sh 13 | 14 | For permanent use you should source it from your bashrc: 15 | 16 | echo "source /path/to/hadoop-completion.sh" >> ~/.bashrc 17 | 18 | You may also add it to your current bash-completion scripts' collection. 19 | 20 | Enjoy. :) 21 | -------------------------------------------------------------------------------- /hadoop-completion.sh: -------------------------------------------------------------------------------- 1 | #!/usr/bin/env bash 2 | 3 | # Licensed to the Apache Software Foundation (ASF) under one or more 4 | # contributor license agreements.
