Subject [jira] Commented: (HADOOP-1375) a simple parser for hbase.
Date Wed, 20 Jun 2007 22:28:26 GMT

stack commented on HADOOP-1375:
-------------------------------

Looking more at the patch.  You need to remove the tabs and instead use spaces, two per tabstop.
  Also, check out the sun coding conventions and study hadoop code.  See how it does spacings
around brackets in particular (You tend to have none whereas hadoop code has one space). 
Given the issues outlined above, I'd suggest adding unit tests -- at least for the content
of your cmd subpackage.  Have your unit tests pass odd parameters and see how your parse handles
them.

> HBase Shell is developed to achieve the following goals. 
>  * Generic Monitoring Function 
>  * A Simplified Import/Export/Migrate Functionality Between different data sources (Hadoop,
HBase) 
>  * A Simplified processing of a logical data model 
>  * A Simplified algebraic operations 
>    (Parallel Numerical Analysis by abstracting/numericalizing points, lines, or plane
data across multiple maps in HBase.)
