>                 Key: HBASE-3293
>                 URL: https://issues.apache.org/jira/browse/HBASE-3293
>             Project: HBase
>          Issue Type: Bug
>         Environment: CentOS 5.5 with Cloudera's CDH3b3
>            Reporter: fnord 999
>            Priority: Major

> When inserting a value into HBase that has a negative timestamp, such as -1, HBase inserts that value without an exception or any kind of other warning if we use the Java API. The value is written to a region and the webinterface of the regionservers shows that there is data in them. 
> However: neither a Scan nor a Get nor any other operation via MapReduce in the Shell or via Java can read that specific value out.
> There would be 2 different fixes in my opinion:
> 1. simply accept the negative timestamps consequently in read and write operations
> 2. if negative timestamps cannot be used, throw an exception when someone tries to insert an invalid timestamp
