Subject [jira] [Commented] (HBASE-10071) support data type for get/scan in hbase shell

cuijianwei commented on HBASE-10071:
------------------------------------

[~stack] Thanks for your comment:). I go through the scan.rb in trunk. The way to specify
custom formatting by column is more general and easy to use. The formatter can also be stipulated
by custom class. Maybe, we can backport this feature into 0.94?

> Users tend to run hbase shell to query hbase quickly. The result will be shown as binary
format which may not look clear enough when users write columns using specified types, such
as long/int/short. Therefore, it may be helpful if the results could be shown as specified
format. We make a patch to extend get/scan in hbase shell in which user could specify the
data type in get/scan for each column as:
> {code}
> scan 'table', {COLUMNS=>['CF:QF:long']}
> get 'table', 'r0', {COLUMN=>'CF:QF:long'}
> {code}
> Then, the result will be shown as Long type. The result of above get will be:
> {code}
> COLUMN                                        CELL                                  
                                                                        
>  CF:QF                                timestamp=24311261, value=24311229
> {code}
> This extended format is compatible with previous format, if users do not specify the
data type, the command will also work and output binary format.
