Resolution: Duplicate
> Frequent calls to printStackTrace() obscuring legitimate problems

> Key: HIVE-10775
> URL: https://issues.apache.org/jira/browse/HIVE-10775
> Project: Hive
> Issue Type: Improvement
> Components: Metastore, Query Processor
> Reporter: Andrew Cowie
> Assignee: Andrew Cowie
> Priority: Minor
> Attachments: HIVE-10775.1.patch
>
>
> When running test suites built on top of libraries that build on top of ...
> that use Hive, the signal to noise ratio with exceptions flying past is
> appalling. Most of this is down to calls to printStackTrace() embedded in
> this library. HIVE-7697 showed someone cleaning that up and replacing with
> logging the exception instead. That seems wise (logging can be redirected by
> the calling test suite).
> So, if you don't object, I'll hunt down the calls to printStackTrace() and
> replace them with LOG.warn() instead. I'm about half way through the patch
> now.
