Peter Vary commented on HIVE-22060:
-----------------------------------
Interesting stuff. I introduced one myself: See: HIVE-21402.
I think there are cases where it makes sense to catch Throwable.
> Replacing "catch Throwable" with a more restricted exception class

> Key: HIVE-22060
> URL: https://issues.apache.org/jira/browse/HIVE-22060
> Project: Hive
> Issue Type: Improvement
> Components: Hive
> Reporter: Ivan Suller

> Catching Throwable considered unsafe in Java. A Throwable can be any Error
> and those are JVM errors after the state of the JVM is not guaranteed thus
> the cleanest way to "handle" the error is to let it kill the current thread.
> I ran a quick scan and found almost 400 "catch Throwable" in the current
> codebase. I opened this ticket as a conversation starter to:
> - discuss if we want to eliminate this issue
> - if we want to do it what's the best way to do it
