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 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.
