[jira] [Created] (ACCUMULO-372) Deprecate selectrow add row option
to scan
Deprecate selectrow add row option to scan
------------------------------------------
Key: ACCUMULO-372
URL: https://issues.apache.org/jira/browse/ACCUMULO-372
Project: Accumulo
Issue Type: Improvement
Reporter: Keith Turner
Fix For: 1.4.0
The selectrow command in the shell would not be needed if the scan command had an option to scan a single row. I propose adding a -r option to scan for scanning over a single row and deprecating the selectrow command. If this is done in 1.4, we can remove the selectrow command in 1.5.

-----------------------------------------
On the other hand, adding options increases complexity and learning curve. It's easier for someone to scan a list of commands then to scan a list of command and their options. The source code would also be marginally more complex as well?

---------------------------------------
It seems if you generalize this argument it could really increase the size of the set of commands. For example we could have the following commands select, selectrow, selectrows, selectrowscolumns, etc. These commands correspond to different combinations of options for the scan command. Increasing the size of the set of commands also impacts the learning curve. Thinking about the list of commands, I opened ACCUMULO-376.
Having two redundant commands means that both need to be tested and maintained. ACCUMULO-363 made me think about selectrow, which is redundant and I believe less used than scan (because it has less functionality). The main issue I worry about w/ deprecating it and removing, is if people are using it in shell scripts. There is no nice way to deprecate things in the shell like there is in Java.
