Subject [jira] [Commented] (HBASE-9035) Incorrect example for using a scan stopRow in HBase book
Date Wed, 24 Jul 2013 11:29:48 GMT

Jean-Marc Spaggiari commented on HBASE-9035:
--------------------------------------------

I agree. However, I will not say that it's generally, but I will more than that it's an easy
and simple way to achieve the same thing, since some people will prefer to reduce the number
of objects created and so avoid to use this filter but add a #FF at the end of the stop row
instead.

> The example of how to use a stop row in a scan in the Section 5.7.3 of the HBase book
[1] is incorrect. It demonstrates using a start and stop row to only retrieve records with
a given prefix, creating the stop row by appending a null byte to the start row.
> This creates a scan that does not include any of the target rows, because the the stop
row is less than the target rows via lexicographical sorting.
