Xiaobing Zhou commented on HIVE-8584: ------------------------------------- Thanks all for comments. After deep investigation, ZLIB mode actually works fine for both platform if qtest output is exact same on both. There are other reasons led to output diff, which will be tracked by other JIRA. I'd mark this as invalid. > 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: Minor > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
