Subject [jira] Commented: (HADOOP-3714) Bash tab completion support
Date Mon, 14 Jul 2008 14:46:32 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3714?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613334#action_12613334
] 

Chris Smith commented on HADOOP-3714:
-------------------------------------

I don't think it's hugely practical (it requires bash and a working Hadoop install, and its
inputs and outputs are env vars) or necessary (it's relatively simple, and flexible enough
to work against 0.16.x and 0.19.x, so I don't think that [m]any changes in the future will
affect it) to unit test this, so would propose that it's included as-is

> The attached Bash script adds support for tab completion of most arguments to the main
Hadoop script ({{bin/hadoop}}). Namely, it allows tab completion of all the command names,
subcommands for the {{fs}}, {{dfsadmin}}, {{job}}, {{namenode}} and {{pipe}} commands, arguments
of the {{jar}} command and most arguments to the {{fs}} subcommands (completing local and
dfs paths as appropriate).
> The file can be dropped into /etc/bash_completion.d/ on Debian-like distros, and it should
then start working the next time Bash is started.
