Re: REST API for Hive queries?

If your requirement is that queries are not going to be run on fly then i
would suggest following.

1) Create Hive script
2) Combine it with Oozie workflow to run at scheduled time and push results
to some DB say MySQL
3) Use some application to talk to MySQL and generate those reports.

Thanks,

Jagat Singh
