> The Parquet FilterPredicate is created and set to the configuration in the 
> ParquetRecordReaderBase.setFilter method. This method is used from the 
> ParquetRecordReaderWrapper constructor through the 
> ParquetRecordReaderBase.getSplit method and expects a JobConf as parameter 
> where it sets the created filter predicate. In the ParquetRecordReaderWrapper 
> constructor, multiple JobConf object is used:
> {noformat}
>     jobConf = oldJobConf;
>     final ParquetInputSplit split = getSplit(oldSplit, jobConf);
>     TaskAttemptID taskAttemptID = 
> TaskAttemptID.forName(jobConf.get(IOConstants.MAPRED_TASK_ID));
>     if (taskAttemptID == null) {
>       taskAttemptID = new TaskAttemptID();
>     }
>     // create a TaskInputOutputContext
>     Configuration conf = jobConf;
>     if (skipTimestampConversion ^ HiveConf.getBoolVar(
>         conf, HiveConf.ConfVars.HIVE_PARQUET_TIMESTAMP_SKIP_CONVERSION)) {
>       conf = new JobConf(oldJobConf);
>       HiveConf.setBoolVar(conf,
>         HiveConf.ConfVars.HIVE_PARQUET_TIMESTAMP_SKIP_CONVERSION, 
> skipTimestampConversion);
>     }
>     final TaskAttemptContext taskContext = 
> ContextUtil.newTaskAttemptContext(conf, taskAttemptID);
> {noformat}
> So we have the jobConf, oldJobConf and conf objects and the getSplit is 
> called with the jobConf object, so the filter predicate will be set into this 
> config object. Based on this code part, the jobConf and oldJobConf should be 
> the same reference inside the if statement, so the newly created conf should 
> also contain the filter predicate. However in the getSplit method the value 
> of the jobConf is changed by the projectionPusher.pushProjectionsAndFilters 
> method, so inside the if statement, the jobConf and the oldJobConf are 
> actually different references. The filter predicate is set in the jobConf, 
> but if the if condition is true, the conf will be created from the oldJobConf 
> so it won't contain the filter predicate.
> Just for reference, this behavior was introduced in 
> [HIVE-9873|https://issues.apache.org/jira/browse/HIVE-9873]. 
> Since the goal of the if statement is only to update the 
> HIVE_PARQUET_TIMESTAMP_SKIP_CONVERSION property in the configuration, it 
> should be using the jobConf where the filter predicate is correctly set.
