>             Project: Hive
>          Issue Type: Bug
>          Components: HBase Handler
>    Affects Versions: 0.11.0, 0.11.1, 0.12.0, 0.13.0

> 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.
