             Summary: Avoid multiple copies of binary data during the 
conversion from Result to Row
                 Key: HBASE-16818
                 URL: https://issues.apache.org/jira/browse/HBASE-16818
             Project: HBase
          Issue Type: Improvement
          Components: spark
            Reporter: Weiqing Yang
            Assignee: Weiqing Yang

In the buildRow() of HBaseRelation, CellUtil.cloneValue will already create a 
copy of the data. If the data type is BinaryType, Another copy is being made 
within Utils.hbaseFieldToScalaType in Utils.scala. Generally, binary data can 
be fairly large, so copying may be an expensive operation.
