> Sqoop currently doesn't support merging of two hive tables. Implement a new
> tool for Sqoop which :
> 1. merges two hive tables. (This will be most commonly used to merge new
> incremental data into an existing hive table)
> 2. should support both partitioned and non partitioned tables
> 3. supports merge on composite keys
> 4. For partitioned tables, merges old partitions and also add new partitions.
> 5. Supports Text/RC/ORC/Seq file formats
> 6. Should make sure that only process is performing merge.
> 7. should be an atomic operation. If it fails at any point , it should revert
> the target hive table to its original state.
