------------------------------------
Hi [~liukailong123] . Thanks for your reporting this issue. Please note that
JIRA descriptions must be written in English to ensure all developers can
understand them.
One question: are you using the MR engine or the Tez engine? The Hive community
has deprecated the MR engine, and the current primary code maintenance is
focused on the Tez engine module.
Additionally, Apache Hive no longer uses patch files for code contributions.
Please submit your code fixes via PR to [https://github.com/apache/hive/pulls] .
Thanks.
