Jonathan Allen created HDFS-4322: ------------------------------------ Summary: Tidy up fs -help Key: HDFS-4322 URL: https://issues.apache.org/jira/browse/HDFS-4322 Project: Hadoop HDFS Issue Type: Improvement Reporter: Jonathan Allen Assignee: Jonathan Allen Priority: Minor
There are a number of issues with the current fs -help implementation that could do with tidying up. 1) Running 'hadoop fs -help' displays the full detailed help for all commands. This produces a large amount of text and makes it hard to find what you're looking for. Better functionality would be: - hadoop fs -usage : shows the basic usage information for all commands - hadoop fs -help : shows usage and brief summary (couple of lines) for all commands - hadoop fs -help <command> : shows full description of the specified command 2) Help text is hardcoded into each command class. This should be replaced by resource files to allow internationalisation. 3) Line breaks are hardcoded into the help text. The help text should be auto-formatted at display time. -- This message is automatically generated by JIRA.
