Jason Dere commented on HIVE-8584:
----------------------------------
When you say not portable, do you mean that an ORC file with zlib compression
created on Linux cannot be read correctly on Windows? Or is the data readable
between platforms, just that the size of the files is different when created on
Linux vs Windows?
> Setting hive.exec.orc.default.compress to ZLIB will lead to orc file size
> delta byte(s) shorter on Windows than Linux

> Key: HIVE-8584
> URL: https://issues.apache.org/jira/browse/HIVE-8584
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.14.0
> Environment: Windows
> Reporter: Xiaobing Zhou
> Assignee: Xiaobing Zhou
> Priority: Critical
> Attachments: HIVE-8584.1.patch, orc-win-none-1.dump,
> orc-win-none-2.dump, orc-win-snappy-1.dump, orc-win-snappy-2.dump,
> orc-win-zlib-1.dump, orc-win-zlib-2.dump, orc_analyze.q
>
>
> repo steps:
> 1. run query orc_analyze.q
> 2. hive --orcfiledump <target_orc_file_generated>
> run 1 and 2 on PST timezone on Linux, and one more time on other timezone
> e.g. CST on Windows.
> Compare two target orc file dumping. Windows orc file is 1 byte shorter than
> Linux one.
> That's the case even if running 1 and 2 on Windows for different timezones,
> however, no problem on Linux.
> The issue only exists by using ZLIB mode, eventually OS native compression
> lib is used.
