--------------------------------
Summary: HBase handler skips rows with null valued first cells
when only row key is selected
Key: HIVE-5277
URL: https://issues.apache.org/jira/browse/HIVE-5277
Project: Hive
Issue Type: Bug
Components: HBase Handler
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.
