[jira] Created: (HADOOP-688) move dfs administrative interfaces to
a separate command
move dfs administrative interfaces to a separate command
--------------------------------------------------------
Key: HADOOP-688
URL: http://issues.apache.org/jira/browse/HADOOP-688
Project: Hadoop
Issue Type: Improvement
Components: dfs
Reporter: dhruba borthakur
Assigned To: dhruba borthakur
The dfs adminsitrative commands (e.g. safemode, report, etc) should be separate from the dfs user commands. The proposal is to remove the following two commands:
bin/hadoop dfs -report
bin/hadoop dfs -safemode
The above two features will be available through a new command:
bin/hadoop dfsadmin -report
bin/hadoop dfsadmin -safemode
This is done so that there is a clean distinction between cluster administrative commands and users command.

[jira] Commented: (HADOOP-688) move dfs administrative interfaces

dhruba borthakur commented on HADOOP-688:
-----------------------------------------
The dfsadmin command is mostly a cosmetic change until we have the 'security model' worked out in detail. For now, -safemode, -report and -decommission will be associated with dfsadmin.
In future, we have to deal with appropriately placing 'format', 'fsck', etc with either dfs or dfsadmin command.

-------------------------------------
I liked the name 'dfsadmin' for this command rather than just 'admin'.

[jira] Commented: (HADOOP-688) move dfs administrative interfaces

Posted by "Yoram Arnon (JIRA)" <ji...@apache.org>.

Yoram Arnon commented on HADOOP-688:
------------------------------------
I wonder...
Since hadoop has no notion of users, security or authentication, commands that can be executed remotely are open to misuse.
since the format command can only be executed locally on the namenode, it's relatively safe - you'd need to login to that node first.
It would perhaps be better to leave safemode as a local only command too, except for reporting.
But then again, anyone can execute rmr /, so this point is perhaps moot.
Had we had some security in place, formatting is most logically colocated with the other admin commands.

------------------------------------------
format command is not invoked currently through dfs shell, right ? It is invoked as bin/hadoop namenode -format.

--------------------------------------------
What about "format"?
Should we place it in dfsadmin group too?
