Subject [jira] Commented: (HBASE-3467) Get doesn't find values with negative timestamps
Date Wed, 02 Feb 2011 18:19:29 GMT

    [ https://issues.apache.org/jira/browse/HBASE-3467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12989740#comment-12989740

Jim R. Wilson commented on HBASE-3467:

I don't want to use negative timestamps per se.  That is, I personally don't have a use case.
 However, I could imagine a use where legacy data is imported where some values are in fact
negative.  Interpreted as a unix timestamp (the default ts interpretation), this would be
events before the epoch.

In any case, if negative values are supported, then they ought to be *really* supported. 
If the architecture changed, and values had to be non-negative integers, that's fine too.
 Either way as long as it's consistent.

> Timestamps are allowed to be negative values, since they're stored as type long.  However,
using the Get object to search for versions by setting setMaxVersions() misses them.
> I'm not sure where this code lives, but my suspicion is that the code which scans for
matching value timestamps has a min value of 0 when it should be using {{java.lang.Long.MIN_VALUE}}.
