------------------------------------
Resolution: Fixed
> HBase region start key straddling a datetime key value gives error or crashes
> -----------------------------------------------------------------------------
>
> Key: TRAFODION-2467
> URL: https://issues.apache.org/jira/browse/TRAFODION-2467
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Affects Versions: 2.0-incubating
> Environment: Any
> Reporter: Hans Zeller
> Assignee: Hans Zeller
>
> There is no simple test case for this, but Wei-Shiun has observed a problem
> that fits the theory, and I was able to force a problem in a debugger.
> The issue is this: HBase creates region start keys, and the length of those
> keys may provide only a part (a prefix) of a column value. So, HBase may have
> a 2 byte region start key of \x07\xCE for a table with a DATE key. This
> provides the year, 1998 in this case, but not month or day. Normally, we
> extend this partial key with zeroes for most data types, including
> date/time/timestamp. However, for these datetime types we need to add logic
> that set the year, month and day fields to 1 if extending the key with zeroes
> would make it 0 otherwise.
