Xiaobing Zhou updated HIVE-8584:
--------------------------------
Description:
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. Windows orc file is 1 byte shorter than Linux one.
Or 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, OS native compression lib is used.

> Setting hive.exec.orc.default.compress to ZLIB will lead to orc file size
> delta byte(s) shorter on Windows than Linux
