Subject [jira] [Updated] (HDFS-2745) unclear to users which command to use to access the filesystem
Date Thu, 16 Aug 2012 01:52:38 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2745?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Wang updated HDFS-2745:
------------------------------

    Attachment: hdfs-2745-1.patch

Attached patch for trunk. Did Eli's suggestions.

* "hdfs dfs" is removed
* "hadoop dfs" has a deprecation message that correctly points at "hadoop fs"
* hadoop-daemon.sh now passes the {{dfs}} command to {{hadoop}}, rather than {{hdfs}}. I grepped
for other usages of "hdfs dfs", and I think we're okay.

If this looks good, I'll make a branch-2 patch as well.

> Its unclear to users which command to use to access the filesystem. Need some background
and then we can fix accordingly. We have 3 choices:
> hadoop dfs -> says its deprecated and to use hdfs.  If I run hdfs usage it doesn't
list any options like -ls in the usage, although there is an hdfs dfs command
> hdfs dfs -> not in the usage of hdfs. If we recommend it when running hadoop dfs it
should atleast be in the usage.
> hadoop fs -> seems like one to use it appears generic for any filesystem.
> Any input on this what is the recommended way to do this?  Based on that we can fix up
the other issues.
