[jira] [Created] (HIVE-10775) Frequent calls to printStackTrace() obscuring legitimate problems

Andrew Cowie created HIVE-10775:
-----------------------------------

             Summary: Frequent calls to printStackTrace() obscuring legitimate problems
                 Key: HIVE-10775
                 URL: https://issues.apache.org/jira/browse/HIVE-10775
             Project: Hive
          Issue Type: Test
          Components: Metastore, Query Processor
            Reporter: Andrew Cowie
            Priority: Minor


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.
