Subject Re: Force users to specify partition indexes in queries
Date Wed, 30 Sep 2015 12:01:29 GMT
hive.mapred.mode = strict is what I need but I want them to restrict to
only one particular index and that too inside a particular max range. I
think hive hooks seems like what I need but my problem is anyone can
override the config in the session.

So if someone discovers that its enforced using postAnalyze hook, then he
can disable it.

Is there a way around this? or my only option is to patch at hive server
code?
