How to arhive hive external tables?

Hi Guys,

Is there a way to check hive external tables which are created 90 days before and drop those tables along with underlying hdfs data. Can this be achieved in unix script?

You might consider looking at the Hive LanguageManual

Code:
https://cwiki.apache.org/confluence/display/Hive/LanguageManual

There you will see, for example, the Beeline – Command Line Shell.

Code:
https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-Beeline%E2%80%93CommandLineShell

You should be able to use this type of Hive CLI in shell scripts to work with Hive, as needed.

Or, you might consider other Hive CLIs, like

HCatalog CLI


Read the Hives CLI docs and experiment until you find a CLI that suits your needs.

You basically have to write a Hive SQL query to get the information you are seeking.

That's part of the Hive documentation.

Execute the CLI command

Code:
desc formatted <database>.<table_name>

on the hive cli.

It will show detailed table information with the creation time.
