-------------------------------------
Summary: Make Debugging Stacktrace More Explicit
Key: HIVE-22529
URL: https://issues.apache.org/jira/browse/HIVE-22529
Project: Hive
Issue Type: Improvement
Reporter: David Mollitor
Assignee: David Mollitor
In some places, the following DEBUG logging was introduced:
{code:java}
LOG.debug("Message", new Exception());
{code}
The purpose of this is to log the stack trace of the Thread calling this debug
logging method. However, the resulting log message includes the following:
{code:none}
2019-11-19T08:13:31,392 DEBUG [Thread] Logger: Message
java.lang.Exception: null
at ....
{code}
To the observer, it appears that there was perhaps some sort of NPE. Add a
message to the Exception being generated to make it more clear that this
"Exception" is for debugging purposes and not an actual error.
