> Key: HIVE-5277
> URL: https://issues.apache.org/jira/browse/HIVE-5277
> Project: Hive
> Issue Type: Bug
> Components: HBase Handler
> Affects Versions: 0.11.0, 0.11.1, 0.12.0, 0.13.0
> Reporter: Teddy Choi
> Assignee: Teddy Choi
>
> HBaseStorageHandler skips rows with null valued first cells when only row key
> is selected.
> {noformat}
> SELECT key, col1, col2 FROM hbase_table;
> key1 cell1 cell2
> key2 NULL cell3
> SELECT COUNT(key) FROM hbase_table;
> 1
> {noformat}
> HiveHBaseTableInputFormat.getRecordReader makes first cell selected to avoid
> skipping rows. But when the first cell is null, HBase skips that row.
> http://hbase.apache.org/book/perf.reading.html 12.9.6. Optimal Loading of Row
> Keys describes how to deal with this problem.
> I tried to find an existing issue, but I couldn't. If you find a same issue,
> please make this issue duplicated.
