    Description

      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
