[jira] [Created] (HIVE-17049) hive doesn't support chinese comments for columns

liugaopeng created HIVE-17049:
---------------------------------

             Summary: hive doesn't support chinese comments for columns
                 Key: HIVE-17049
                 URL: https://issues.apache.org/jira/browse/HIVE-17049
             Project: Hive
          Issue Type: Bug
          Components: CLI
    Affects Versions: 1.2.1
         Environment: hive 1.2.1 in HDP 
            Reporter: liugaopeng


1.  alter table stg.test_chinese change chinesetitle chinesetitle tinyint comment '中文';
2.  desc stg.test_chinese;
Result: chinese comment "中文" becase "??"

also, if i modify the comment via hive view, it will still display the messy code "??".

I did some testing, but cannot fix it, such as:
1. change the hive.COLUMNS_V2 to UTF-8 chartset.
2. append the characterEncoding=UTF-8 to hive_to_mysqlmetadata url 

i found some ideas that need to apply some patch to fix it, but seems they all effects in 0.x version, i use the 1.2.1 version.

Please give some guidence.....
