             Summary: [hbase-connectors] Duplicate result when searching HBase by Spark
                 Key: HBASE-27488
                 URL: https://issues.apache.org/jira/browse/HBASE-27488
             Project: HBase
          Issue Type: Bug
          Components: hbase-connectors
            Reporter: ZheHu


I've used hbase-connector for querying HBase table by Spark, and the following issue is what I've encountered recently:

When I run SQL:
{code:java}
select * from hbase_tabe where rowkey in ('r1', 'r2') or rowkey='r1'
{code}
I've got duplicate row "r1" in results.
In HBaseTableScanRdd, buildGets method forms two duplicate GET request for rowkey "r1". I think we might need a Set to make sure duplicate rowkey won't be request.
