vvysotskyi commented on issue #1284: DRILL-6438: Remove excess logging form 
some tests.
URL: https://github.com/apache/drill/pull/1284#issuecomment-391652009
 
 
   @ilooner, could you please remove other places in tests where results are 
printed using `System.out.println()`. For example, in `TestHiveUDFs`, 
`ExpressionTest`, `TestPartitionSender`, `TestSimpleProjection`, 
`TestConvertFunctions`, `TestFragmentChecker`, `JdbcTestActionBase`, 
`ITTestShadedJar` it also may be removed; for every HBase test its result is 
printed for now.
   Mongo and hive tests have a large output, it would be fine to reduce it.
   
   Also, may be changed value of the option `drill.test.query.printing.silent` 
to reduce output.
