> Converge the insert path of Hive tables with data source tables

>                 Key: SPARK-18243
>                 URL: https://issues.apache.org/jira/browse/SPARK-18243
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL

>
> Inserting data into Hive tables has its own implementation that is distinct 
> from data sources: InsertIntoHiveTable, SparkHiveWriterContainer and 
> SparkHiveDynamicPartitionWriterContainer.
> I think it should be possible to unify these with data source implementations 
> InsertIntoHadoopFsRelationCommand. We can start by implementing an 
> OutputWriterFactory/OutputWriter that uses Hive's serdes to write data.
> Note that one other major difference is that data source tables write 
> directly to the final destination without using some staging directory, and 
> then Spark itself adds the partitions/tables to the catalog. Hive tables 
> actually write to some staging directory, and then call Hive metastore's 
> loadPartition/loadTable function to load those data in.
