             Summary: Hive jdbc driver should support 
PreparedStatement.addBatch and executeBatch
                 Key: HIVE-16221
                 URL: https://issues.apache.org/jira/browse/HIVE-16221
             Project: Hive
          Issue Type: Improvement
            Reporter: Lukas Waldmann


Currently when inserting data to Hive DB using jdbc driver you can insert 
multiple rows only by concatenating strings  of values, which is very 
ineffective and for tables with big number of columns can lead to insertion of 
just one or few lines at once because of String length limitation.
Furthermore each insert creates a new file on HDFS increasing the strain on the 
resource manager. 
Batch processing should solve this problem as multiple inserts can be merged to 
one by the driver.
