-------------------------------------------------------------

bq. Merge of files in orc_merge9.q is not happening anymore, is that expected?
This is expected and is due to {{Writer version mismatch}}. Looks like writer version is updated in ORC 1.5.6

bq. The min value for some columns in stripe statistics in orc_file_dump.q has changed, is this expected?
This is also expected. There is a bug fix in ORC 1.5.6 which fixes incorrect min/max
