As indicated in an existing answer by @hduraiswamy there are some things you can do:
1. Give multiple insert commands in parallel, and they will automatically be executed sequentially
2. Writing multiple files to a directory and then creating a hive table on top of the folder, see the aforementioned answer
If this does not work for you, you can of course also work with a non-external hive table.
