-------------------------------------
Summary: HBase Timestamp filter never gets converted to a
timerange filter
Key: HIVE-24544
URL: https://issues.apache.org/jira/browse/HIVE-24544
Project: Hive
Issue Type: Bug
Components: HBase Handler
Reporter: Fabien Carrion
Attachments: timerange.patch
When I was trying to apply a timestamp filter, I get the wrong data. A request
such as:
```
select key, ts from t1 where ts >= '2020-12-01 00:00:00' and ts < '2020-12-02
00:00:00';
```
returns value with ts < '2020-12-01 00:00:00'
After investigation, it looks like the timestamp filter is never used in the
HiveHBaseTableInputFormat.getRecordReader method, which is used to create the
actual mapreduce job.
But it used in the HiveHBaseTableInputFormat.getSplitsInternal method, which is
used to create the mappings tasks.
So I copy the code from the second method in the first.
I attached a small patch. That's a little hacky and I am not sure I respect the
philosophy of the component. But it works.
