Subject [jira] [Updated] (HIVE-8801) Make orc_merge_incompat1.q deterministic across platforms
Date Sun, 09 Nov 2014 05:23:33 GMT

     [ https://issues.apache.org/jira/browse/HIVE-8801?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Prasanth J updated HIVE-8801:
-----------------------------
    Attachment: HIVE-8801.1.patch

Added one more file to partition. Now there are 3 files written with 0.11 version and 3 files
written with 0.12 version. The outcome of merge will be 4 files independent of which input
file is chosen first.

> orc_merge_incompat1.q tests for ORC fast file merge when there are incompatible files
in a partition. The outcome of merge will be dependent on order of the files that CombineHiveInputFormat
passes on to OrcFileMergeOperator. Since the ordering of files is not guaranteed the result
of merge operation will be different across different OS'es.
