be more selective for beeline getLogs
Thejas M Nair created HIVE-8785:
-----------------------------------
Summary: HiveServer2 LogDivertAppender should be more selective for beeline getLogs
Key: HIVE-8785
URL: https://issues.apache.org/jira/browse/HIVE-8785
Project: Hive
Issue Type: Bug
Reporter: Gopal V
Assignee: Thejas M Nair
A simple query run via beeline JDBC like {{explain select count(1) from testing.foo;}} produces 50 lines of output which looks like
{code}
0: jdbc:hive2://localhost:10002> explain select count(1) from testing.foo;

{code}
A more complex query like Query27 produces 800+ lines of unnecessary logging.
This is unreadable and in-fact slows down the beeline JDBC client.
