Yi Zhang created HIVE-26881:
-------------------------------
Summary: tblproperties are not cleaned from jobConf for TezTask
Key: HIVE-26881
URL: https://issues.apache.org/jira/browse/HIVE-26881
Project: Hive
Issue Type: Bug
Components: Hive
Affects Versions: 3.1.3
Reporter: Yi Zhang
Users uses xmlserde to read xml files, when user create table they specify
tblproperties and it uses jobConfÂ
[https://github.com/VenkataNU/hivexmlserde/blob/main/src/main/java/com/ibm/spss/hive/serde2/xml/XmlInputFormat.java#L72]
in Tez mode, after 1st query run, those tblproperties are part of Driver.conf,
so then next query runs, the jobConf of the tez job contains the tblproperties
from last run. This is cause wrong results since the next query should not use
last query's tblproperties.
