             Summary: 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
            Assignee: 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
