Minor Description
Carbon1.3.0 Concurrent Insert overwrite-update: User is able to run insert overwrite and update job concurrently.
updated data will be overwritten by insert overwrite job. So there is no meaning of running update job if insert overwrite is in progress.
Steps:
1: Create a table
2: Do a data load
3: run insert overwrite job.
4: run a update job while overwrite job is still running.
5: Observe that update job is finished and after that overwrite job is also finished.
6: All previous segments are marked for delete and there is no impact of update job. Update job will use the resources unnecessary.
