[jira] Commented: (HADOOP-1828) [Hbase Shell] Switch Command for sub-shell

Izaak Rubin commented on HADOOP-1828:
-------------------------------------

Hi Yoon,

I understand your desire to communicate with the other shell project members, and I agree that comments like these are a good way of doing so.  However, I think I should clarify that I myself am not working on the sub-shell implementation; I was only asked to review the patch and give my feedback.  

The main concern I had with your patch was that it was a bit open-ended and ambiguous.  The patch itself didn't make the direction or use of the sub-shell clear; it would need additional patches to make an understandable implementation of sub-shell.  It's just my opinion that a patch should effect a full, complete change without having to depend on future patches or issues.

-------------------------------------

Thank you for your comment, Rubin.

I wanted to use patch mailing list as a way for more effective communication among shell project members. 
I may have been mistaken for using it for that purpose. 

I will instead only issue a patch when there is a significant amount of work/implementation is done, 
but I wonder if it may be more difficult for us to communicate

Please let me know if this is what you've implied in your last email.

Hi there,

I'm attaching a new patch (shell_2.patch) which is a cleaned-up version of your patch (shell.patch).  I applied shell.patch to my local copy and diff-ed to get shell_2.patch, which is significantly smaller.  Shell.patch had a lot of redundant adding and removing: it would remove large sections of code only to re-add them with minor changes.  I think there must have been something wrong with the way you generated the patch.

As I was looking through the patch and my patched local copy, I noticed that you didn't add the altools and rdf commands to the help list (although the commands themselves and their shells worked fine).  Also, the other commands you added (like projection, group, sort, ...) seemed out of place.  Is there a need to have them in the patch when (for now) they have no corresponding action?

The altools and rdf sub-shells only seem to mimic the commands of the original shell.  I think think these sub-shells might be coming before their time; they don't really have a purpose until there are unique commands and capabilities for them to have.

[jira] Updated: (HADOOP-1828) [Hbase Shell] Switch Command for sub-shell

Posted by "Izaak Rubin (JIRA)" <ji...@apache.org>.
     [ https://issues.apache.org/jira/browse/HADOOP-1828?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Izaak Rubin updated HADOOP-1828:
--------------------------------

    Attachment: shell_2.patch

Hi there,

I'm attaching a new patch (shell_2.patch) which is a cleaned-up version of your patch (shell.patch).  I applied shell.patch to my local copy and diff-ed to get shell_2.patch, which is significantly smaller.  Shell.patch had a lot of redundant adding and removing: it would remove large sections of code only to re-add them with minor changes.  I think there must have been something wrong with the way you generated the patch.

As I was looking through the patch and my patched local copy, I noticed that you didn't add the altools and rdf commands to the help list (although the commands themselves and their shells worked fine).  Also, the other commands you added (like projection, group, sort, ...) seemed out of place.  Is there a need to have them in the patch when (for now) they have no corresponding action?

The altools and rdf sub-shells only seem to mimic the commands of the original shell.  I think think these sub-shells might be coming before their time; they don't really have a purpose until there are unique commands and capabilities for them to have.
