Description

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:

scan 'table', {COLUMNS=>['CF:QF:long']}
get 'table', 'r0', {COLUMN=>'CF:QF:long'}

Then, the result will be shown as Long type. The result of above get will be:

COLUMN                                        CELL                                                                                                           
 CF:QF                                timestamp=24311261, value=24311229

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.
