Subject [jira] Commented: (HADOOP-2984) Distcp should have forrest documentation
Date Wed, 11 Jun 2008 22:30:45 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2984?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12604367#action_12604367
] 

Tsz Wo (Nicholas), SZE commented on HADOOP-2984:
------------------------------------------------

- Provide the full class name for DispCp once in the beginning for the document.

- Add a line to explain the command name distcp

- Some examples have long single line commands.  These long single line commands got wrapped
up in the docoument, especially in the pdf.  It is good to use \ to break the long command
into several lines.  e.g.
Use
{noformat}
hadoop distcp               \
    hdfs://nn1:8020/foo/a   \
    hdfs://nn1:8020/foo/b   \
    hdfs://nn2:8020/bar/foo
{noformat}
instead of
{noformat}
hadoop distcp hdfs://nn1:8020/foo/a hdfs://nn1:8020/foo/b hdfs://nn2:8020/bar/foo
{noformat}

- I think it is more clear to add a command prompt for shell commands
e.g.
{noformat}
bash$ hadoop distcp ...
{noformat}
