Negative timestamps can be inserted without fail but not read again
-------------------------------------------------------------------
Key: HBASE-3293
URL: https://issues.apache.org/jira/browse/HBASE-3293
Project: HBase
Issue Type: Bug
Affects Versions: 0.89.20100924
Environment: CentOS 5.5 with Cloudera's CDH3b3
Reporter: fnord 999
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
