> OrcFileMergeOperator creates a new ORC file and appends the stripes from
> smaller orc file. This new ORC file creation should retain the same
> configuration as the small ORC files. Currently it does not set the orc row
> index stride and file version. Also merging of stripe statistics to file
> statistics was incorrect leading to issues like in HIVE-9080
